I have a complain. I have solve Question B & C of Codeforces Round 931 & it was succesfully run in pretests, but after the contest it's showing runtime error. & submitting the same code after the contest it is succesfully accepted. Please tell me how it's happened. harsh__h
C: During Contest & after contest
B: During Contest & after contest
[Later Edited]: I have got the problem that it's due to vector size declaration of 30, but i am confused why it didn't give runtime error on test 1 instead of this later cases.
