Question: give a precise count of the number of multplications used...

Question details

Give a precise count of the number of multplications used by the fast exponentiation routine. (Hint. Consider the binary representation of N)

long long expo (long long x, unsigned int n) if (n = 0) if (n1) ii: ((n % 2) :::: ()) return 1; return X; return expo(x*x, n/2); return expo(x*x, n/2) * x; else
