Recursive Programm in QTSpim

Use QtSpim to implement the code below to implement a recursive sequence an = an−1 + bn−1 bn = an−1 − bn−1 with a0 = b0 = 0 and a1 = 2, b1 = 1. Your code should prompt the user to enter the value of n and display the results in the console. Note that you should use recursion to implement the code. Also determine the smallest positive value of n for which your code results in an error. Explain the cause of error.
