guys please help me answer this 1) N factorial can be defined as the product of all integer from 1 to N and it is denoted by the symbol N!.0! (zero factorial) is defined a 1. write a program that will input N and would call the function factorial that will return N factorial. (determine first if N is a non-negative integer) 2) an integer is considered prime if its only factors are 1 and itself. 1 can be considered a prime integer because its factors are 1 and only 1. Write a program that will input a non-negative and would call the function prime that returns 0 for true and 1 for false. (precondition: test if the entered value is non-negative) thanks in advance for your answers !! D
