Hello everyone,
I'm looking forward to some problems in competitive programming which used some calculus techniques (derivatives, integrals, ....).
Would you please show me some problem :D :D :D ? The solution maybe just use only calculus, not using some hard techniques like FFT. Thanks a lot :D
Hello Codeforces,
My sister implemented the solution for 279B — Books here:
And so amazing !!!! This solution is accepted. I've tried but cannot create the test case to prove this solution is wrong. Can you help me ? Or can you prove that this solution is correct
Thank you a lot for your help.
