Canvas Pattern Generation

You are given a number of test cases, and for each test case, a single integer m representing the size of a canvas. Your task is to generate a pattern for each canvas in the following way:

For a canvas of size m, the pattern consists of m rows. The first row contains 1 number, the second row contains 2 numbers, and so on. The numbers in each canvas are consecutive natural numbers starting from 1. In other words, the numbers for the i-th row range from $$\frac{(i-1)i}{2}+1$$ to $$\frac{i(i+1)}{2}$$.

Output the pattern for each test case. Separate the output of consecutive test cases by a blank line.

inputFormat

The first line of input contains an integer T which denotes the number of test cases. This is followed by T lines where each line contains one integer m, the size of the canvas for that test case.

Example:

2
3
4

outputFormat

For each test case, output the generated pattern. The pattern for each case consists of m lines, with the i-th line containing i consecutive numbers separated by a single space. Print a blank line between the outputs of consecutive test cases.

Example output for the above input:

1
2 3
4 5 6
1
2 3
4 5 6
7 8 9 10
