WebPython’s bitwise NOT operator ~x inverts each bit from the binary representation of integer x so that 0 becomes 1 and 1 becomes 0. This is semantically the same as calculating ~x == -x-1. For example, the bitwise NOT expression ~0 becomes -1, ~9 becomes -10, and ~32 becomes -33. As you go over the article, you can watch my explainer video ... WebDec 17, 2024 · Method 3: We can also use the Tilde operator ( ~) also known as bitwise negation operator in computing to invert the given array. It takes the number n as binary number and “flips” all 0 bits to 1 and 1 to 0 to obtain the complement binary number. So in the boolean array for True or 1 it will result in -2 and for False or 0 it will result ...
