Hello, good people. Hope you all are well. :) How to increase my thinking ability? I think day by day my thinking ability not so much increased. Yeah I know I am weak at math and lot of lackings in high school math. Let me tell an example about my thinking ability, when I open a problem in like cf B type problem my mates understand the problem very quickly like 10-15 minutes but I didnt understand the problem even in 1-2 hours. I know here many people have good knowledge about math and also competitive programming. So for competitive programming purpose please give me some advice so that I can increase my logical thinking ability. :) Thanks a lot for read my long boring post.

Sorry for my so so poor English :)

Hy all, :) I am struggling to learn basic dp for a while. Its pretty hard for me to understand rcursion. As we all know recursion is the mother of dynamic programming. So, It would be great if you suggest me some good resources for beginner where you learned firstly dp or suggest some classical dp problem with solution so that I will understand the concept or suggest any other way :) Thanks a lot :)

Is that a better way to solve USACO traing gateway problem before doing CF contest? As you see I am a novice solver. After done one contest I feel I am not much skillfull here. I feel I should do something before doing this type of contest. It will be definitely great If you guys share your beginner level strategy that I can follow. Thanks a ton. Sorry for my poor English.
