This is a very simple code so I didn't expect it to take more than 1000 ms. How could I optimize it? https://codeforces.me/contest/380/submission/116189186

Your time complexity is O(m*n). That's why TLE!!
your code can run at most n*m operations where n is the length of the string and m is the number of queries. since you loop from l to r a total of m times, this can go to at most 10^11 operations which will tle.
