Q1. Consider the following mathematical equation which is defined for all non-negative integers m and n. Write a recursive function in C that computes and returns the value calculated based on the mathematical equation given two arguments m and n.* n+1 A(m, n) = Am 1,1) (A(m 1, A(m, n 1)) if m = 0 if m > 0 and n = 0 if m > 0 and n > 0 Your answer Q2. Write a complete C program to test the recursive function that you have written in Q1. Prompt user for two integers m and n and print the output on the screen. Use the first digit of your id number as m, and the last digit of your id number as n. For example, my id number is 1001060515, then my m is 1 and my n is 5. Upload the complete C program as .txt and the screenshot of your output as an image. * 1 Add file Q3.
