i recently encountered a problem — 1208B - Уникальность
I have use a simple Binary search approach for that problem
I have 2 submissions , both are using Binary search and both have same worst case time complexity of O(N^2 log^2(N)) but one gives TLE and the other gets AC
AC submission — 146479295
TLE Submission — 146333083
can anyone tell me why this is happening?
I mean, the AC code is already close to the time limit, and using sets has bigger constant factor than just sorting, it's pretty reasonable for the second code to TLE
Time complexity is more of an estimation than a guarantee that your algorithm will be fast
