This is a program that analyzes how many islands are in a list and how big the biggest one is. An island is a connected group of #. It doesn't count if they are connected just by corners. This first item of the list, is the rows and columns. The first number of the output is the number of islands and the second number is the biggest island. In order to have it analyze your own map, you have to go into the project and import your own and then press the green flag.
All code by me! Prompt from Scratch Olympiad. There really isn't any art in this, but I made all the sprites.
