when i can use unordered_map and when i can't?

Revision en3, by THERE_IS_NO_RETURN, 2021-02-14 21:06:56

hi i am learning dynamic programming and i wonder what are the cases when i can use unordered_map to store results without fear from TLE ? what is time complexity for inserting and finding out if the result stored or not ? i have searched and find many answers but it was complicated for me because i am totally beginner.
