I would like to share much valuable lesson I learnt today in Div2- 986 contest. I wasn't able to Solve B, and that costs me not solving C and D.↵


**For anyone, not being able to solve an easier problem, is more frustrating than not being able to solve hard problem.**↵


Chronology:↵

**1) Mistakes 2 wrong submissions in B:**↵

Since 10 ^ 18 * 10 ^ 18 was too large, I wrote of writing code in c++, and convert it to python. [Which Got TLE](https://codeforces.net/contest/2028/submission/290909092) . First wrong submission started panic mode.↵

Then, I started to find O(1) solution for Problem B, and missed edge cases. Wasn't able to solve B for first 50 minutes of the contest and I couldn't control emotionally.↵

**2) Read Problem C, 
found it very easy. Submitted, which failed on C**↵

[I submitted this C,](https://codeforces.net/contest/2028/submission/290932958) during the contest. just by changing one of `<=` condition to `<` gave me AC. I would have easily debugged this, if I would have been calm.↵


**3) I misread D, implemented wrong, couldn't even pass pretest-1**↵
[As I have mentioned in this comment](https://codeforces.net/blog/entry/136061?#comment-1217509), I had missed one crucial detail the the problem D.↵

After the contest, I solved B,C,D all together. I figured out, that C and D I was quite close to solve. Even if I had solved C and D, and left B unsolved during the contest, I would have been satisfied with my performance.↵
