Thank you to everyone who attended this year's Harker Programming Invitational (HPI)! Novice and Advanced problems have been uploaded to the Gym for upsolving.

Harker

Pretty straightforward: most languages have a standard library function for finding a given substring in a string, so you can just use that.

def solution(s):
    if "harker" in s:
        return 1
    return 0
    
T = int(input())
 
for _ in range(T):
    s = input()
    print(solution(s))
