@harshini_18
here plzz refer the following code

t = int(input())

while t > 0:
    s = input()
    hpy = False
    v = {"a", "e", "i", "o", "u"}
    for i in range(len(s) -2):
        if s[i] in v and s[i+1] in v and s[i+2] in v:
            hpy = True
            break
            
    # Your code goes here
    t -= 1
    if hpy:
        print("Happy")
    else:
        print("Sad")
