WebThe complexity of bitwise operations is O ( s i z e 32) or O ( s i z e 64), it depends on the architecture of your computer. Problems P1. Different numbers — You are given a sequence of N ≤ 10 7 numbers, each from interval [ 0, 10 9]. How many different values appear in the sequence? Don't use set or unordered_set because they quite slow. solution WebSource code that does bit manipulation makes use of the bitwise operations: AND, OR, XOR, NOT, and bit shifts. Bit manipulation, in some cases, can obviate or reduce the need to loop over a data structure and can give many-fold speed-ups, as bit manipulations are processed in parallel, but the code can become more difficult to write and maintain.
