Write a function prodDigits, that takes a non-negative integer and returns the product of its digits.

• Your function should be named prodDigits.

• Your function has one input argument of type integer.

• Your function should return the product of the digits: an integer value.

• Your function should not print/output anything

Note: You do not need to write the main(), theinclude, or namespace commands, you only need to write the function definition.

Examples:

• For input 1456, the function should return 120. (Explanation: the product of digits 1 * 4 * 5 * 6 = 120).
• For input 111, the function should return 1. (Explanation: the product of the digits 1 * 1 * 1 = 1).
