I understand your frustration, and it's a common feeling when tackling complex problems like this. Finding these insights often comes down to a combination of experience, practice, and a systematic approach to problem-solving. Here's how you can develop the ability to identify key points and d...
Hello DPforces! A contest for DP practice and all problems are from Codeforces. I hope you all would like this. Link 0 UMMK 2 years ago 1 Comments (1) Write comment? ARMINIUS 2 years ago, # | 0 Helpful problems thanks → Reply ...
There are some few problems I came across likeFishandVirus synthesiswhich seem to have solutions with BFS traversal and typical DP minimization/maximization function. I want to practice this technique because normally when I think of coding a DP solution I only think of DFS traversal, any ideas ...
Codeforces 1076F Summer Practice Report——贪心+dp 题意:你有n个纸条,现在你要用0和1去写满这些纸条(每个纸条只能写一行),每个纸条都给出了一个x和一个y,表示要求写的0的数量和1的数量,并且规定任何时候都不能有超过k个0连续,任何时候都不能有超过k个1连续,注意假设写完一个纸条和它后一个纸条是连续的...
