School project help

**starcoveredhoney** · February 28th, 2022, 06:10 PM

Hello. I am in desperate need of help for a school project. It is due today at 11:59pm CDT. I genuinely do not even know where to begin.

Lab Description : Ben loves Kitties and his kitties are running free. You need to help Ben identify where his kitties are so he can get them all rounded up.
Each cell in the boolean matrix that contains a kitty will be set to true. Each cell that contains no kitty will be set to false. Use Math.random() to randomly place the 0s and 1s in the grid – try multiplying by numbers larger than 2 if you want fewer kitties in the grid.
As you work to help Ben recover his lost kitties, you will create an integer matrix that stores the number of kitties near each cell. Each cell that contains a kitty is set to 9. All other cells are set to the value of how many kitties are around them. This integer grid will be used to determine the best location from which to start collecting Ben’s kitties.
Bonus Challange: Write a method to find the best place to drop a kitty collecting robot. The robot will fan out in all directions and collect all kitties within a 3 cell radius. Your method should return the location of the best place to drop the robot.
Boolean matrix(all random)

What is the logic have you worked on to solve the problem?

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

My dad and I just sat down and worked on it together for a bit and this is what he gave me to work on. I'm still really confused.
