WebFor example number 10 first appears in the sequence in position 55 (the elements are numerated from one). Find the number on the n -th position of the sequence. Input The only line contains integer n ( 1 ≤ n ≤ 10 14 ) — the position of the number to find. Note that the given number is too large, so you should use 64 -bit integer type to ...

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. Show how to wire up a 4-bit shift register using D flip-flops.

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). 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.
