+Consider the following 4×4 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×N pattern of the same kind (containing integers 1 through N2).
+
+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.
