CSmall algorithms & bit operations

Count set bits in an unsigned integer

C: Clearing the lowest set bit on each iteration counts only one iteration per set bit.

C✓ Tested
CSmall algorithms & bit operations

Generate a bounded Fibonacci sequence

C: Keep only the two previous values instead of using exponential recursive calls.
