Example:-    
1.>
Input:-                          Output:-
4  4                          1  2  3  4  8  12  16  15  14  13  9  5  6  7  11  10
1  2  3  4
5  6  7  8
9 10 11 12
13 14 15 16

2.>
Input:-                     Output:-
5 3                         1  2  3  6  9  12  15  14  13  10  7  4  5  8  11                 
1  2  3
4  5  6
7  8  9
10 11 12
13 14 15

3.>
INput:-                    Output:-
3 5                      1  2  3  4  5  10  15  14  13  12  11  6  7  8  9
1  2  3  4  5
6  7  8  9  10
11 12 13 14 15

Note:- In example 2 and example 3  we will get wrong Output but here due to modification(endRow>StartRow , endCol>StartCol)
we are getting right Output......
