Fast exponentiation algorithms, The simplest implementation of exponentiation requires N-1 multiplication operations, where N is an exponent base, Despite all the power of modern computers, this method does not suit us since we will use numbers for the exponent, even larger than standard 64-bit integers, E,g,, Mersenne Prime number: 618970019642690137449562111 used as default exponent …

Modular exponentiation Recursive

Modular exponentiation Recursive Difficulty Level : Medium, Last Updated : 19 Apr, 2021, Given three numbers a, b and c, we need to find a b % c, Now why do “% c” after exponentiation, because a b will be really large even for relatively small values of a, b and that is a problem because the data type of the language that we try to code
