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