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.

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.

WebA flip operation is one in which you turn 1 into 0 and 0 into 1. For example: If you are given an array {1, 1, 0, 0, 1} then you will have to return the count of maximum one’s you can … WebInitially the answer is 0. At first we will try to make the highest bit in the answer into 1 (I think this doesn’t need a proof). If we want the i − th bit in the answer to be 1, we need for every element of c the i − th bit to be 1 and for this in every optimal pair we need (ai & (1 ≪ i)) ⊕ (bi & (1 ≪ i)) = (1 ≪ i). WebA shift register is an n-bit register that shifts its stored data by one bit position for each cycle of the clock. Shift registers can be used to perform multiplication, division, and serial-to-parallel conversion, among many other tasks.
