Hmm I guess this is not s C question, but anyway this is my strategy

strategy 1

1. print first line
2. remove first line
3. take transpose of matrix
4 go to step 1 till matrix is not empty

strategy 2

assuming a function printcircle(mat) that prints boundary circle of a
matrix beginning at first element
i=0,j=0
1. printcircle(&(mat[i][j]))
2. i++,j++
3. goto step 1 till matrix is not empty
