Answer 1

def has_duplicate_digits(n):
    strn = str(n)
    
    if len(strn) % 2 == 1:
        return False
    
    # start, stop, step
    for i in range(0, len(strn) - 1, 2):
        print(strn[i] , " ", strn[i + 1])
        if strn[i] != strn[i + 1]:
            return False
            
    return True

n = 7799225511

if has_duplicate_digits(n):
    print("yes")
