remove the first for loop as string is an array of chars. you dont have to push chars into another array to get the last one. just reassign a pre defined variable. s=input() #taking input string n=int(input()) #taking frequency a='' for i in s: if(s.count(i)==n): a=i if(a): print(a) else: print(-1)

This problem is asked in a practice contest in skillrack. In that private test cases are not passing.
