In this HackerRank in a String! the problem, For each query, print YES on a new line if the string contains hackerrank, otherwise, print NO.
Problem solution in Python programming.
#!/bin/python3 import sys word ="hackerrank" q = int(input().strip()) d = () for a0 in range(q): s = input().strip() n = len(s) # your code goes here p = 0 wi = 0 for wi in range(len(word)): if wi < 9: p = s.find(word[wi], p) +1 if p == 0: break if wi == 9: print("YES") else: print("NO")
