eid mubarak to all .hope this eid bring happiness to you all
From yesterday i have just noticed that when i submit any solution, it is much faster now to check code with test case.any one know any thing??
Very often i do not understand problem statement.i have solved remarkable number of problems but i do not get over this problem. even in contest it happens if i can understand the problem i could solve it coz i know the technique.need an advice
Holy Eid mubarak to all!!Hope the day will be full of food after 1 month of ramadan.(:
Suppose i want to find the kth number of a sequence.the number will consist only of 2,4,6,8.How can i find it??any technique ?? Detail.
http://codeforces.net/contest/437/problem/C
for second case if i remove 3 first cost=100 then remove 4 cost=100+100=200;(3 already removed) and 2 then will cost=200+100=300 and 1 cost=300+0=300; i find 300 ,but the result is 400, am i missing something ?
