Iterate over a fixed C array using a size-derived element count.
C✓ Tested
Sum typed values with reduce
Accumulate numeric array elements.
reduce✓ Tested
Test whether an unsigned value is a power of two
C: A nonzero power of two has exactly one set bit.
C✓ Tested
Test whether any or all values match
C#: Any and All short-circuit instead of materializing filtered collections.

Arduino / C: XOR flips selected bits and leaves all other bits unchanged.
Arduino / C✓ Tested
Toggle an output using an explicit software state
Arduino / C: Keep the intended output state in a Boolean variable.
Arduino / C✓ Tested
Transform a vector into a separate result
C++: Pre-size the output before writing through its iterator.
C++✓ Tested
