BitWeaving-S

A simple C++ implementation of BitWeaving, a technique that exploits the parallelism available at the bit level in modern processors. BitWeaving operates on multiple bits of data in a single cycle, processing bits from different columns in each cycle. For more details, please refer to https://dl.acm.org/doi/10.1145/2463676.2465322
