I guess having score of $$$\text{D2} < \text{D1}$$$ can result in something like this..

      I don't have a level !!!

      I just want to convey that if the problem difficulties are like (~800 + ~1000 + ~1300 + ~1600 + ~2000 + ~2500+) then it considered as stable one, because if you are pupil then you can try for 1300-1600 problems or expert then try for 2000.

      But if problem difficulties are like (~800 + ~1000 + ~1400 + ~2300 + ~2500+), then it is difficult for expert level contestant to go for 2300 directly, as it is very difficult for them.

        Excuse me, but since when 1300-rated C and 1600-rated D are considered a good contest?(Or a "normal", or "stable" or whatever you call it.)

        A normal round level was always 1600-1800 rated C, 1800-2200 rated D (sometimes even way harder and it's okay)

        Maybe it sounds rude, but if someone is too weak for average problem C level it means he has to become stronger, but not problem has to become easier. And I think I should disappoint you with fact that D was never expert level. Rather CM or even Master, but not expert (well, if we talk about normal contest, but not latest contests with 1600-rated D's).

        It's stupid and very sad seeing how rounds are becoming easier and easier (in most cases, not talking about each of them), and you, people get used to rounds being easier and ask for even easier problems?

          I gave just an example ( JUST AN EXAMPLE, I DON'T WANT TO SAY THAT THE DIFFICULTIES SHOULD EXACT LIKE THAT ), the main issue for this contest is the difference of difficulty level between problem C and D.

          A good round in my opinion is the one in which the no. of accepted solutions of a problem is x/2 or x/3 of the accepted solutions of the previous problem. But here the accepted solutions of D1 are 10 times lesser than C. So definitely, it's not a stable contest.

          I agree with you on the part that D is CM level but it should be near around 2000-2100 at max. Also, are you seriously saying that C should be 1800? If that happens then div 2 will rather become boring (or say speedforces) till specialist level as all of them would be able to do B but hardly anyone could do C.

          Yeah, rounds are becoming easier nowadays (at least A, B and C) but it's not at all good that to make the round harder, give D, E, and F as 2300+. It's still a Div 2 round and it should be challenging for all div 2 participants rather than being challenging only for the participants who have almost reached div 1.

            I'm seriously saying that, because it's not my desire to make C difficult for specialists, but because any old round has C with >= 1600 rating (with least exceptions). Yes, 1600 then isn't 1600 now, but still, average problem C then (1-2 and more years ago) is absolutely not what average C looks now. Come on, every last contest's C has 1500-3000 solves. I wouldn't call this "ballanced".

            Today's contest isn't exeption. Huge solve difference between C and D is not because D is undersolved but because C is oversolved.

            And I personally liked today's C (maybe because it brought me to top 270 today), but still number of C's solves tells a lot. Same as I liked today's D because it was indeed good difficult problem, which didn't make this div 2 a contest with 1000 D solves. (as it happened few previous contests, yes?)

              Well if you look at the official standings, C is solved by nearly 1850 participants, it is nice considering that it was a 6-problem contest and over 10.5k people have given the contest officially.

              I still consider D undersolved as D problem should be something which have around 500-600 AC solutions during contest. If you are comparing it with old contests, they are 5-problem contests where C comes with a rating >=1600.

              I also liked today's C as I have seen dp in C after a long time in codeforces which is a good thing. And since I was unable to get D till now so it's a good question for me. ( ̄▽ ̄)"

I solved C using bitset with O(n^3/32).

Is that the correct solution???

If yes, then C is a completely failure.

    Let's look at board. There are integers $$$l$$$ and $$$r$$$, such that only for all $$$i \in [l, r]$$$, there is path with cost $$$i$$$. Calculate such $$$l$$$ and $$$r$$$ using simple dp.

    And also, bad corner case, if $$$n+m$$$ is even, the answer is No.

      You will have all paths with cost $$$i$$$ for $$$i \in$$$ {$$$l,l+2,l+4 , ... , r-2, r$$$} not every path. $$$l$$$ and $$$r$$$ will be even if $$$n+m$$$ is odd so your code will still work.

        I'm guessing so. This is because if you pick any "corner" (i.e. down-to-right or right-to-down) and switch it (i.e. DTR->RTD or RTD->DTR), you'll have a delta of -2, 0, or +2 exactly in the path sum. Also, all paths would have even sum when (n+m) is odd.

        So my intuition was that you can "move" the path from minimum to maximum so that the path sum reaches to 0 at a particular point.

    I made calculating $$$dpMIN[x][y]$$$ = minimum possible sum at $$${x, y}$$$ and $$$dpMAX[x][y]$$$ = maximum possible sum at $$${x, y}$$$. If $$$(n + m - 1)$$$ is even, then at finish position $$${n, m}$$$ we can get any value in range $$$[ dpMIN[n][m]; dpMAX[x][y] ]$$$, so we should check if $$$dpMIN[n][m] <= 0 && 0 <= dpMAX[n][m] <= 0$$$.

    It's obvious that MIN and MAX values may come from different "paths" but we can always "mix" them in some proportions to get any intermediate values.

        Its an O(n*m) D.P,

        Basically you try to find maximum number of ones that you can pick on the path starting at (i, j) and ending at (n, m) for each (i,j).

        so base case is dp[n][m] which is 1 if arr[n][m] = 1 and 0 otherwise.

        and the recurrence relation is dp[i][j] = (arr[i][j] == 1) + max(dp[i+1][j], dp[i][j+1]).

        We need to take care of boundary cases properly.

    I am sorry if my idea to the solution was discussed before, but I think my solution is a bit different from faraday_vij's solution.

    If the path length i.e N + M - 1 is odd, we can't make a path out of it.

    If the path length i.e N + M - 1 is even, then:

    We need (path length / 2) 1s and equal number of -1s to make the path-sum 0. I calculated the maximum number of 1s and -1s I can encounter for an arbitrary [i, j] till [N - 1, M - 1]. I kept 2 2D arrays, one which will keep count of 1s and another of -1s. Then for each [i, j], I calculated the number of 1s which I can encounter till the last cell and similarly calculated the same for -1s. Then we can either perform DFS or BFS and check for a cell, if it is possible to go till the last cell depending on the number of 1s and -1s required and taking a look from the pre-calculated array. If any cell doesnot satisfy the requirements, we can't make a path out of it, so we just cancel out this cell and try out another.

    My DFS solution: 161125001

    My BFS solution: 161118932

    Well, you can analyze the maximum path, then move the path by one block towards the minimum path and you can see that you can go through all path sums from max path to min path. This is because you can never jump by more than -2 or +2 by moving one block of the path

    Problem C Define "value" of the path as the sum of its visited cells. Find the minimum value of path (call it $$$m$$$) and maximum value of path (call it $$$M$$$). If parity of length of path (i.e. $$$(n+m-1)$$$) is even and $$$m<=0$$$ and $$$M>=0$$$. Then I claim, it is possible to get every value path of even parity between $$$m$$$ and $$$M$$$. Why?

    Consider the optimal path in which minimum value is obtained. Now, I claim that any other path can be constructed by following a sequence of operations which involves deleting some block $$$(x,y)$$$ and replacing it with $$$(x+1,y)$$$ or $$$(x,y+1)$$$. Every time, the value of the path changes by $$$+2$$$ or $$$-2$$$ or $$$0$$$. This is really easy to verify by drawing on some piece of paper, I'm not going to describe a formal algorithm here.

    So to get from path value $$$m$$$ to path value $$$M$$$. You do a sequence of operations which changes the value of path by $$$0$$$, $$$+2$$$ or $$$-2$$$. So, you have to go through all paths of same parity ($$$m$$$) between $$$m$$$ and $$$M$$$.

    Observe that for odd n, Mike is going to win by simply taking the entire pile in the beginning. For even n, note that Mike cannot interfere with Joe's pile and vice versa, so the one who runs out of stones after removing one at a time will lose. You can check this by finding the minimum value of the array that appears first and check whose pile it is.

            Let Mike take all stones in the first pile. Then since $$$n$$$ is odd what ends up happening is that eventually Joe will have to pick from the first pile which is empty.

            Since the piles are nonempty at the start this strategy always works.

            Example: $$$(3, 4, 2)$$$. Mike takes $$$3$$$, Joe takes $$$x$$$, Mike takes $$$y$$$. Then Joe has to take from pile 1 which is $$$0$$$.

    For any vertex with $$$k$$$ leaves($$$k > 1$$$), you must take $$$k-1$$$ of them in your query. Now for vertices with only one child which is a leaf, consider that vertex itself to be a leaf. This is because if you can identify that vertex then you can identify the leaf. Take sum over all to get answer. For the special case when the graph is a straight line, your answer is 1.

    Among all paths, compute the minimum and maximum possible sum of values. Every value between them with equal parity is possible. Why? Because any path can be transformed into any other path by repeatedly changing two consecutive moves, and each of these elementary moves changes the value by at most 2.

    But to be honest, I think this observation is quite difficult for a beginner to come up with.

I submit the question by making a matrix of int and I got the wrong answer but later I submitted using a matrix of long i.e accepted.

According to the question aij >= -10^9 && aij <= 10^9 , but still i can store it in int. please please consider my first submitted code.

thanking you Abhinandan Kumar

can someone please explain how does bfs/memoized search work for C ? I don't seem to understand how is it not worse than O(n*m)

UPD: weak system tests again, almost all such submissions TLE on test 47 now.

In this round, I have received unexpected warning from CodeForces plagiarism checker.

That says "Your solution 161070788 for the problem 1695C significantly coincides with solutions ArChErr/161069277, sadi_74/161070788, Basilhijaz/161080032."

My approach for problem C was quite straight forward.Just using dp to calculate maximum and minimum possible sum for every cell. Whoever solved the problem using this idea, it is quite possible to match their solutions. I have explored the submissions of other people from common standing, and I found other submissions that are quite similar. It does not mean that we all shared our code among us, it is just that our approaches were same.

I am requesting MikeMirzayanov and jdurie to look into this unexpected warning.

Today I received a message saying that my solution for problem C of Codeforces Round #801(Div-2) coincides with the solution jreddy4499/161075183 . The other user's code and my code has the same template which is openly available to anyone on Geeks for Geeks website. Link for the Template This is a clear mistake. Even the editorial's solution matches with my solution.

I request MikeMirzayanov to please look into this .

I too have received a plag message for problem C.

"Your solution 161082044 for the problem 1695C significantly coincides with solutions ZZZGen/161067422, excalibur1702/161082044, ivetrof5/161085438, Crime_and_Punishment/161088440, normie_coder/161092870, roshan2412/161110694"

The algo used is basic DP. The variable names are indeed similar but you can check my previous submissions. I've used similar variable names, as well as the same spacing / indentation / coding style in the past as this submission. Haven't used a public online IDE either.

Not to mention, ZZZGen/161067422 has the verdict "Passed" while the other submissions, including mine, are still "Skipped", which I don't understand at all.

I already contacted jdurie and he/she/they said they can't do anything about it. What should I do?

I request MikeMirzayanov to look into this matter. A few other people have also posted regarding false plag checks in this very question.

I've been falsely accused of plagiarism this round. Got nuked from contest. Messaged Mike about it but still haven't received a reply. Is there anything else I can do? Really sucks to be punished for no reason like this ;-;.
