Write a program( preferably in C++) using the extended Euclidean algorithm to find the multiplicative inverse of a mod n. Your program should allow user to enter a and n. Note: For this question please make sure the code compiles and runs, it is not copied and pasted from elsewhere( I will be checking!). Thanks
