Help !!!
https://codeforces.net/contest/1926/submission/275328157 & https://codeforces.net/contest/1926/submission/275328315 both these code correspond to the same logic, the difference is just in using map and unordered map, But first one, which is done by using unordered map results in TLE. But why? As far as I knew unordered_map requires lesser TC w.r.t map. Kindly correct me if I am wrong.

The worst case time complexity of the operations on unordered_map is O(n).SO it will give you TLE.

Thank you so much!
Using unordered_map on large amount of data will result in "blowing up" which increases the time complexity. There are already several blogs on this, might want to check this out
Yeah, I got this!
