After trying so hard, I could not solve problem A or problem B today, they were both so hard, help me how could i have solved it.

I thought there would be some logical solution for A, i thought of using STack, binary search in problem A.

But the solution is loops for 100 times? I dont understand what is purpose of such problems.

I want to quit cp after today.

ANy tips on how to solve problems will be appreciated.

Thanks

Solving problems like A and B can actually be disheartening to face at times. Note that problem difficulties are not precisely consistent across contests (i.e. div2 A and B in contest 1 may be much easier than A and B in div2 contest 2). If you look at the standings, people generally struggled with A and B for a little while -- more than usual. I also did. I recommend 2 things then:

  • Systematic process of thinking. This refers to solving problems by repeating a 2 step process again and again: (1) make observations, (2) what is the next intuitive step from here (e.g. different cases, something needs to be optimized). This applies to B in particular from today's contest, but all problems roughly require this pattern of thought.

  • Contest strategy. This refers to jumping between problems depending on your strengths and weaknesses in problem topics or perhaps depending on the particular problem. I spent 30 mins on A and B without solving them, then jumped to C and solved that in a few minutes since I know binary search very well. Then I gained some confidence in the time I had left to take the time to solve A and B.

In all cases, keep practicing -- I know losses can be disheartening.

pretty much a womp-womp situation, seeing you submitting problems once in different languages with AI-lookalike variable names and all other stuff
