Print a matrix in a spiral form starting from a point

Given a matrix of size n*m, and a point P(c, r). Print the matrix in a spiral form(clockwise) starting from the point P.

Examples : 

Input : mat[][] = {{1 2 3},
 {4 5 6},
 {7 8 9}}
 Point P = (0, 2)
Output : 3 6 5 2 9 8 7 4 1
The starting point is top left which
is 3.

This problem is mainly an extension of print a matrix in spiral form.

Implementation:

3 6 5 2 9 8 7 4 1 

Time Complexity: O(max(low_row,low_column) x max(high_row , high_column)) 
Auxiliary Space: O(1)
