You have a lot of small integers in an array. You have to multiply all of them. You need not worry about overflow and range, you have enough support for that. What can you do to speed up the multiplication on your machine?

Question

Accepted Answer

To speed up multiplication of small integers in an array, we can use bitwise operations and parallel processing.

Use bitwise operations like shifting and ANDing to perform multiplication faster.
Divide the array into smaller chunks and perform multiplication in parallel using multi-threading or SIMD instructions.
Use lookup tables for frequently used values to avoid repeated calculations.
Use compiler optimizations like loop unrolling and vectorization.
Consider using specialized libraries like Intel MKL or OpenBLAS for optimized matrix multiplication.
