Female Coding Pioneer

Ada Lovelace, the first programmer and a visionary mathematician, was chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was fond of sequences. During her studies she came across an infinite sequence that was generated using the following algorithm, starting with an empty sequence.

Starting from step number 1, in step number i, the integer i is appended to the sequence exactly k times where k is equal to the number of set bits in i.

Given an array query of n integers, for each query, find the value at the given index of the array assuming indexing starts at 0Report an array of n integers where the xth integer represents the answer to the xth query.

Example

Given, n = 2 and query = [4, 10], the sequence is generated as follows.

Step NumberBinary Representation of NumberNumber of set bits in NumberSequence
111[1]
2101[1, 2]
3112[1, 2, 3, 3]
41001[1, 2, 3, 3, 4]
51012[1, 2, 3, 3, 4, 5, 5]
61102[1, 2, 3, 3, 4, 5, 5, 6, 6]
71113[1, 2, 3, 3, 4, 5, 5, 6, 6, 7, 7, 7]

In the generated sequence, the value at index 4 is 4, and at index 10 is 7. Hence the answer is [4, 7].

Function Description

Complete the function getValueAtIndices in the editor below.

getValueAtIndices takes the following arguments:

    int queries[n]: the queries

Returns

    int[n]: the answers to the queries

Constraints

  • 1 ≤ n ≤ 105
  • 0 ≤ query[i] ≤ 109

Input Format For Custom Testing

The first line contains an integer n, the number of elements in queries.

Each of the next n lines contains an integer, queries[i].Sample Case 0

Sample Input For Custom Testing

STDIN          FUNCTION
-----          --------
3        →     queries[] size n = 3
2        →     queries = [2, 3, 6]
