Unable to find why your code is failing and this code is passing.

Python Code 
for i in range(int(input())):
    n = int(input())
    s1 = {'cakewalk','simple','easy','easy-medium','medium-hard'}
    s2 = {'cakewalk','simple','easy','easy-medium','hard'}
    s3 = {'cakewalk','simple','easy','medium','medium-hard'}
    s4 = {'cakewalk','simple','easy','medium','hard'}
    contest_set = set()
    for i in range(n):
        contest_set.add(input())
    if contest_set & s1 == s1 or contest_set & s2 == s2 or contest_set & s3 == s3 or contest_set & s4 == s4:
        print("Yes")
    else:
        print("No")

Try this test case.

Input:

1
7
simple
hard
cakewalk
easy-medium
easy
medium-hard
hard

Expected Output:

Yes

Your Output:

No

It was a silly mistake.

it is enough to check if any one of the sets (s1, s2, s3, s4, s6) is a subset of s5
