Sort Integers in Submatrix

The program must accept an integer matrix of size R*C and two integers X, Y as the input. The integers X and Y represent the bottom-left position of a submatrix of size X*(C-Y+1). The program must sort the integers in the specified submatrix. Then the program must print the revised matrix as the output.

Boundary Condition(s):
2 <= R, C <= 50
1 <= Matrix element value <= 10^5
1 <= X <= R
1 <= Y <= C

Input Format:
The first line contains R and C separated by a space.
The next R lines, each contains C integers separated by a space.
The R+2^nd line contains X and Y separated by a space.

Output Format:
The first R lines contain the revised matrix.

Input:
5 6
90 49 77 41 32 21
67 71 69 14 94 28
60 87 92 42 88 26
34 75 33 66 51 86
38 99 15 81 97 55
3 4

Output:
90 49 77 14 21 26
67 71 69 28 32 41
60 87 92 42 88 94
34 75 33 66 51 86
38 99 15 81 97 55

Explanation:
Here R=5, C=6, X=3 and Y=4.
The submatrix of size 3*3(i.e., 3*(6-4+1)) with the bottom-left position as (3, 4) is highlighted below.
