WebDec 20, 2024 · EDIT: I've tried doing the following: change all the numbers into binary bits and store all the bits in deques. Afterwards, check if one of the bits are 0 in the given range, and if there is one 0, then said bit returns 0 value. I did get a correct answer. However, it's still not efficient enough. Here is my code WebFor unsigned integers, the bitwise complement of a number is the "mirror reflection" of the number across the half-way point of the unsigned integer's range. For example, for 8-bit unsigned integers, NOT x = 255 - x , which can be visualized on a graph as a downward line that effectively "flips" an increasing range from 0 to 255, to a ...
