Question

I have one application of WinForms which inside list box I am inserting name and price..name and price are stored in two dimensional array respectively. Now whe

Answer 1

For converting 1D indices to and from 3D indices:

(int, int, int) OneToThree(i, dx, dy int) {
    z = i / (dx * dy)
    i = i % (dx * dy)
    y = i / dx
    x = i % dx
    return x, y, z
}

int ThreeToOne(x, y, z, dx, dy int) {
    return x + y*dx + z*dx*dy
}
