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.

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

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

1 <= T <= 100
1 <= n <= 105
