题目描述
Consider the following $4 \times 4$ pattern:
1 2 4 7
3 5 8 11
6 9 12 14
10 13 15 16
You are given an integer $N$. Print the $N \times N$ pattern of the same kind (containing integers $1$ through $N^2$).
-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first and only line of each test case contains a single integer $N$.
-----Output-----
For each test case, print $N$ lines; each of them should contain $N$ space-separated integers.
-----Constraints-----
- $1 \le T \le 10$
- $1 \le N \le 100$
