Ahem..

First of all we are sorry that it's too late.

Let me tell you a common problem I face in contests.

"I read the problem statement and I understand that pretty well. But either I don't know how to approach or I get stuck in fixing bugs."

Sometimes it takes more than an hour to fix the bugs and the contest ends.

This is a common scenario for beginners like me.

For a beginner normally there are 3 types of problems in a contest ( especially in onsite ones). (Maybe these are true for experts too :p)

1. They understands the problem but can get AC because of lack of bug-free coding skills.
2. They understands nothing of a problem.
3. They understands well and get AC for 1-3 problems.
