WebSome of the very common use case bit hacks: 1) Swapping two numbers: x = x ^ y y = x ^ y x = x ^ y. How does it work? Because of XOR property y^ (x^y) = x. and x^ (x^y) = y. (be … WebTask. There are N coins kept on the table, numbered from 0 to N – 1. Initially, each coin is kept tails up. You have to perform two types of operations: 1) Flip all coins numbered between A and B inclusive. This is represented by the command “0 A B”. 2) Answer how many coins numbered between A and B inclusive are heads up.

WebOutput. For each test case, output two lines. The first line should contain the lexicographically largest string you can obtain. The second line should contain n integers f 1, f 2, …, f n, where f i is the number of times the i -th bit is selected. The sum of all the integers must be equal to k.
