Here I'm doing searching work only.unordered_map<>takes O(1) for searching and map<>takes O(long) for searching so I didn't get that why I'm getting tle. Here is my code link -:

#define boost() reserve(1024)#define fast() max_load_factor(0.25)you can use this template (credit goes to Arpa) too to speed up umap in main :
umap_name.fast();umap_name.boost();Still it can give TLE on some specific case na

unordered_map is implemented using hash table because of hash collision it can take O(n) time in some cases
