WebApr 4, 2013 · In the extreme case, you could always convert a one's complement by looking if the most significant bit is 1. If it is, you set it to 0, invert all the bits ~ and then increment the result by one. If the most significant bit was 0, you already have a two's complement (as both are equivalent, when positive) – Nolonar Apr 4, 2013 at 14:38 WebJun 8, 2014 · The challenge: Given a random input string of 1's and 0's such as: 10101110101010010100010001010110101001010 Write the shortest code that outputs the bit-wise inverse like so: 01010001010101101011101110101001010110101 code-golf Share Improve this question edited Jan 3, 2024 at 11:13 sergiol 3,378 1 13 31 asked Jun 7, … WebA Computer Science portal for geeks.
