# 68. Write a Python program to calculate the sum of the digits in an integer.

def sumOfDigsInInt(integer):
    sum = 0

    # Method 1:
    # counter = integer
    # while counter > 0:
    #     if int(integer/10) > 0:
    #         sum += integer % 10
    #         integer = int(integer/10)
    #     else:
    #         sum += integer
    #         break

    # Method 2
    # numSize = len(str(integer)[:])
    # print("Int has %d digits" % numSize)
    # for i in range(numSize):
    #     sum += integer % 10
    #     integer = int(integer/10)

    # Method 3
    for i in str(integer)[:]:
        sum += int(i)
    
    return sum

num = int(input("Input an integer: "))
print("Sum of individual digits within that intger is = ",sumOfDigsInInt(num))
