Avoid Squares Please CodeChef Solution

Problem – Avoid Squares Please CodeChef Solution

You are given an integer N.

Print a permutation PP of [1,2,…,N] such that the following condition holds:

• For any index i (1≤i<N), Pi​×Pi+1​ is not a perfect square.

If there are multiple correct answers, you may print any of them.

Note: A permutation of [1,2,…,N] is a rearrangement of those numbers.

Input Format

• The first line of input contains a single integer T, denoting the number of test cases. The description of T test cases follows.
• The first line of each test case contains an integer N – the length of the required permutation.

Output Format

For each test case, print N space-separated integers representing the valid permutation on a single line.

If there are multiple correct answers, you may print any of them.

Constraints

• 1≤T≤500
• 2≤N≤500

Sample 1:

Input: 
3
2
3
4
Output: 
2 1
3 1 2
4 2 3 1

Explanation:

Test case 1: 2×1=2 is not a perfect square. Note that [1,2] is also a valid answer for this case, and will be accepted.

Test case 2: 3×1=3 and 1×2=2 are not perfect squares.

Test case 3: 4×2=8,2×3=6,3×1=3 are all not perfect squares.
