Instructions ent the extended Euclidean algorithm to find the greatest common divisor of any two positive integers a and b, as well as values for s and t such that s xa +t xb gcdla,b). It should also provide an accurate response if the user enters a zero It should implement the pseudocode provided in the text. It should allow the user to enter two integers a and b Your program should output the intermediate values of q, r, r1, r2, s, st, s2,t, t1, and 12 for each step. It should return the greatest common divisor and values for s and t Challenge task: Provide error checking to confirm that the input is not negative. This is an individual assignment.
