i am making a skript that makes it so uyou place plocks in a pattern here is moer code for stone and andesite

    if block below the event-block is stone:
        set block to andesite
    else if block above the event-block is stone:
        set block to andesite
    else if block north the event-block is stone:
        set block to andesite
    else if block east the event-block is stone:
        set block to andesite
    else if block south the event-block is stone:
        set block to andesite
    else if block west the event-block is stone:
        set block to andesite

on place of andesite:
    if block below the event-block is andesite:
        set block to stone
    else if block above the event-block is andesite:
        set block to stone
    else if block north the event-block is andesite:
        set block to stone
    else if block east the event-block is andesite:
        set block to stone
    else if block south the event-block is andesite:
        set block to stone
    else if block west the event-block is andesite:
        set block to stone```

i need this for concrete and concrete powder for example red concrete replaces block next to it with red concrete powder
i need this for all the concrete varients is there any way i can make it in less code?

here is an example of what the code does

Ohh no

See how each condition has the same result? Why not use an if any

Or honestly, loop blocks in a radius of 1
