* Input description:
* Problem description and output: compile a Java application,
* Function: You can call the element with the largest median value in a two-dimensional array to the element in the upper left corner. Then, you can call the element with the smallest value to the element in the lower right corner. For example:
1 4 5 6
7 2 10 11
9 8 12 3,
Reconciliation result
12 4 5 6
7 2 10 11
9 8 3 1
