Project Euler Problem 016

Statement

2^(15) = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.

What is the sum of the digits of the number 2^(1000)?

Solution

Extremely simple in a language like Python.

if __name__ == '__main__':
    num = 2 ** 1000
    result = 0
    while num > 0:
        result += num % 10
        num //= 10
    print("The result is:", result)
