You need to implement printCorners method. It should print all corner elements of the twoDimArray in the following order: left to right and top to bottom.
The elements must be separated by space and printed as an example below.
Input array:
1 0 2
0 0 0
3 0 4
Printed corners:
1 2
3 4
Notice, that you must always print 4 corners, for example:
Input array:
1
2
3
Printed corners:
1 1
3 3
