I would suggest you search a bit of the documentation to understand more of the language but anyway I'll try to explain what you can do

You can do a for loop going through the a array and inside you do a for loop going through the b array, if a[index] = b[index2] you break out of the a loop and put the index in a new array that you initialized before

If you need more help than that say but I recommend going through more documentation and a few videos and learn a bit more the basics
