Binary NOT

Perform bitwise NOT on a binary value.

Example: 1010

Definition: Flips every bit in the input binary string (0 → 1, 1 → 0).

Conversion formula

Bitwise NOT (one's complement):
Flip each bit in the input: NOT(0) = 1, NOT(1) = 0.

For an N-bit value x, NOT(x) = (2^N - 1) XOR x

Example (4-bit):
Input:  1010
Output: 0101

Example (32-bit IPv4-style):
Input:  00000000000000000000000000001101 (13)
Output: 11111111111111111111111111110010 (bitwise NOT of 13)
