# Question: Write a Python program to check whether a number is divisible by both 5 and 11.

def main(num: int) -> None:
    if num % 5 == 0 and num % 11 == 0:
        print(f"{num} is divisible by both 5 and 11.")
    else:
        print(f"{num} is not divisible by both 5 and 11.")

if __name__ == '__main__':
    main(55)
    main(22)
    main(10)
    main(121)
