def is_kaprekar(n):
    if n == 1:
        return True
    
    square = n * n
    str_square = str(square)
    
    for i in range(1, len(str_square)):
        left = int(str_square[:i]) if str_square[:i] else 0
        right = int(str_square[i:]) if str_square[i:] else 0
        
        if left + right == n and right != 0:
            return True
    
    return False

# Input from the user
num = int(input("Enter a number: "))

# Check and display result
if is_kaprekar(num):
    print(f"{num} is a Kaprekar number.")
else:
    print(f"{num} is not a Kaprekar number.")
