Write a program that implements the modular exponentation algorithm seen below. Follow the instructions above.

Write a program that implements the modular exponentiation algorithm 5 on page 254 of the textbook. You should implement the algorithm as a function long long modexpo(int b, const int a[], int m); wherethe aray a] is the binary representation of the exponent which should also be implemented as a function Converts n to binary *Eparam n the inputted number to convert param al the outputted binary representation as an array void convert2binary(unsigned int n, int a) Assume the maximum number of bits is 32 for the array. Also, check that the inputted n doesn't exceed 232-1
