Your question is Binary to Decimal Conversion. Start with the requirements on the right.
Run and submit as often as you like. When you're ready, talk me through your approach or go straight to the code.
Nissan Motor control software represents some vehicle signals as nonnegative integers stored within a known fixed width. Given an integer value and a bit width width, flip every bit in that width: 0 becomes 1, and 1 becomes 0. Return the resulting value as a decimal integer.
The width is significant because leading zero bits are part of the signal. For example, value = 5 with width = 4 represents 0101, not 101.
Do not convert the value to a binary string. Use bitwise operations and a mask containing width one-bits.
Implement invert_signal(value, width):
value and width.value within exactly width bits.0 <= value < 2**width.def invert_signal(value, width):
