WebEfficient Exponentiation For HUGE Numbers (I'm Talking Googols) I am in the midst of solving a simple combination problem whose solution is 2^ (n-1). The only problem is 1 <= n <= 2^31 -1 (max value for signed 32 bit integer) I tried using Java's BigInteger class but It times out for numbers 2^31/10^4 and greater, so that clearly doesn't work ...

WebFirst write the exponent 25 in binary: 11001. Remove the first binary digit leaving 1001 and then replace each remaining '1' with the pair of letters 'sx' and each '0' with the letter 's' to get: sx s s sx. Now interpret 's' to mean square, and 'x' to mean multiply by x, so we have: square, multiply by x, square, square, square, multiply by x.

This method is an efficient variant of the 2 -ary method. For example, to calculate the exponent 398, which has binary expansion (110 001 110)2, we take a window of length 3 using the 2 -ary method algorithm and calculate 1, x , x , x , x , x , x , x , x , x , x , x . But, we can also compute 1, x , x , x , x , x , x , x , x , x , which saves one multiplication and amounts to evaluating (110 001 110)2 WebJul 6, 2024 · A Computer Science portal for geeks.
