A little confusion on unordered map complexity
Problem: https://mirror.codeforces.com/contest/978/problem/F
Solution 1(TLE): https://mirror.codeforces.com/contest/978/submission/98839909
Solution 2(AC): https://mirror.codeforces.com/contest/978/submission/98859922
Here, in solution 1, I used 3 unordered map and getting TLE but when I used 2 unordered map on solution 2 it gets AC. Why this happened while unordered map searches, inserts, and deletes elements in O(1)?
