Implementations left without caching: bc, C, Pascal, R, and Scheme.

Use the same function to determine whether a number is a power of 2. 2021-10-26T15:42:52+00:00 Abigail abigail@abigail.be 2021-10-26T15:42:52+00:00 6f22a777308b07dcd433baf9ce525ba9dd95eedb We now use the same algorithm (but implemented in different languages) to determine whether a number is a power of 2. This replaces the preprocessed powers of 2, and lookup tables.
