Compilation error

You miss a comma in the 2D array "grid". Look: https://code.sololearn.com/copHFV6ap99v/?ref=app

sometimes connection gets lost , might thatswhy error occured //working for me , 5000

Usually compiler write to us which kind of error we have 😃

As they said, it works fine. However, I've noticed lately when using the Code Playground that I get that error once in awhile even though there is no actual error. I believe it's something taking place on the server end when it's compiling and that's just the output you're getting fed back. That may also be why it doesn't feed you back any information on the compile error. Just my guess on it.

Works well for me! (Output is 5000)

output 5000 working

It is working without any error!
