wat is meant by traversing a matrix

and also can any one tell me the concept of traversing a "matrix helically"??

When you traverse something, you walk it. When you traverse helically, you walk in a spiral. Thus, in the case of a matrix, you'd walk something like so:

789
612
543

Start at one, end up at nine.

wat is meant by traversing a matrix

well a matrix is usually represented by a two dimensional array....traversing would mean looping through it ie:

#include <stdio.h>

int main()
{
        int r, c, matrix[6][6];

        for (r=0;r<6;r++)
                for(c=0;c<6;c++)
                        matrix[r][c]=(c+r) % 2;

        for (r=0;r<6;r++) {
                printf("{");
                for(c=0;c<6;c++)
                        if (c==0)
                                printf("%d",matrix[r][c]);
                        else
                                printf("%3d",matrix[r][c]);
                printf("}\n");
        }

        return 0;
}

sets up a matrix and displays it.
