Added three small, self-contained bit-manipulation utilities and extended doctests for two existing files. New files include author metadata (Author: Basuki Nath).
Changes are minimal, follow repository contribution rules (doctests, small functions, no external deps), and are intended as low-effort additions suitable for first-time contributors.
Files changed
Added:
Added:
parity.py - parity(number) returns 1 for odd parity, 0 for even parity.
next_power_of_two.py - next_power_of_two(n) returns smallest power of two >= n for positive integers.
rotate_bits.py- rotate_left32(x, k) and rotate_right32(x, k) for 32-bit rotations.
Modified:
is_power_of_two.py - added extra doctest examples (edge cases).
count_number_of_one_bits.py- added extra doctest examples (additional cases).
