What is the best ide for cp. Why do many people use vim ??

Why in codeforces we cant see the failed testcases? If the test case no is large for ex (failed on test 1023). Their should be an option to download the text case. It can save a lot of time and efforts . Also large cases when n(array size)>=100 their should be an option to download the test case.

Today after a lot of practice , I finally became pupil .Looking forward to improve more and reach my goals.

How is the idea to take a break from codeforces and learn dsa only, for 1-2 months?? Will this help??

Hlw, everybody i recently reached pupil and now my next target is to be specialist and then blue(expert). Shall i do DP,Trees,Graphs to become specialist and if yes then how much?? Or, i dont require them to reach cyan?? At last what should i learn to become blue afterwards sequentialy?
