Bit Inversion and Swapping | Dataford Interview Questions

Tell me about how you would invert bits in two bytes and swap them.

Implement invert_and_swap(byte1, byte2). Each input is an unsigned 8-bit integer. Invert all eight bits in both bytes, then exchange their positions. Return the result as a two-element list in swapped order. The inversion must remain limited to eight bits, so Python's unlimited integer representation must be masked appropriately.

Example: invert_and_swap(0b00001111, 0b10101010) returns [0b01010101, 0b11110000].

Constraints

byte1 and byte2 are integers
0 <= byte1 <= 255
0 <= byte2 <= 255
Each input represents exactly one unsigned byte

Function Signature

def invert_and_swap(byte1, byte2):
