PROGRAMMING:Matrix transpose
Given an n × The integer matrix of n (1 < = n < = 20) is transposed according to the main diagonal, that is, row and column are exchanged, and then the transposed matrix is output
###Input format:
There are several groups of test data, which are processed to the end of the file. Enter n for the first line of each group, and enter n for the N lines starting from the second line × N elements in a matrix (no more than 2 integers per element).
###Output format:
Each group outputs transposed matrix, and each element outputs by 3 character positions.
###Input example:
Here is a set of inputs. For example:
```in
three
42 75 52
95 62 34
34 9 59
```
###Output example:
The corresponding output is given here. For example:
```out
42 95 34
75 62 9
52 34 59
```
