The first line of the input contains an integer $$$t$$$ ($$$1 \leq t \leq 629$$$) — the number of test cases. Then $$$t$$$ lines follow, each containing a single integer $$$n$$$ $$$(3 \leq n \leq 2\cdot10^5)$$$ — the length of the array.

For each test case, output one line containing $$$n$$$ distinct integers that satisfy the conditions. If there are multiple answers, you can output any of them.
