hello codeforces community At the last contest (codeforces round Div2 1101 ) , i tried to solve C2 before C1 and take 8 wrong submissions on test 16 in C2 at the last three minutes I submitted solutions for C2 and C1 the same same code but The strange thing is that the C1 get accepted and C2 wrong on test 16 and the most strange thing is that when I saw test 16 it was 1000 test cases and the correct answer is 43 so i thing n may be small may this test can be put in C1 if n <= 3000 and make my code fails this is my submission on C1 : https://mirror.codeforces.com/contest/2232/submission/376701327 and this for C2 : https://mirror.codeforces.com/contest/2232/submission/376701241

can the author explain why that happen and sorry for bad english
