TLE in 2 test cases of Highest Frequency (Hashing)

#1

My program gives a TLE in two of the test cases and I am not sure why is that. Please help.

use unordered map
simply iterate ur map . store element which has highest frequency . if two elements has same frequency then pick that which has smaller data value
