Modular Exponentiation for large numbers - GeeksforGeeks

WebSep 19, 2008 · For instance, if you want to compute x^15, the method of exponentiation by squaring will give you: x^15 = (x^7)*(x^7)*x x^7 = (x^3)*(x^3)*x x^3 = x*x*x This is a total of 6 multiplications. It turns out this can be done using "just" 5 multiplications via addition-chain exponentiation. WebThis technique of raising a number to a large exponent is often used in competitive programming.
