Easy Accuracy: 47.98% Submissions: 929 Points: 2

Given an integer ‘n’, generate the first ‘n’ terms of the Connell Sequence.
Connell Sequence is the sequence formed with the first odd number, i.e 1 as its first term. The subsequent terms of the sequence are made up of the first two even numbers, i.e 2 and 4, followed by the next three odd numbers, i.e 5, 7 and 9, followed by the next four even numbers, i.e 10, 12, 14 and 16 and so on …. the sequence continues.

Input:
The first line contains an integer T, the number of test cases. For each test case, there is an integer n. 

Output:
For each test case, the output is a Connell Sequence containing n terms.  

Constraints:
1 <= T <= 100
1 <= n <= 105

Example:
Input:

2
6
12
Output:
1 2 4 5 7 9​
1 2 4 5 7 9 10 12 14 16 17 19
