This is pretty simple. You get a list of 5000 by 5000 grid of ones and zeros, and you have to print the number of islands in the grid.
I found a really old prng… can you exploit it?

Can you help me? I had a flag that I bought at the store, but on the way home, I dropped parts of it on some roads! Now some roads have strings of text, and I can’t tell which are part of my flag. I’m very smart and efficient (but somehow not smart or efficient enough to keep my flag), so I know that I took the fastest way from the store back to my house.
We have created the securest possible RSA algorithm! (Put your flag in the flag format.)

Do you like lasers? I like lasers! Here’s a warmup: create a program that factors the one number given as input. Output factors on one line in ascending order (or just leave them on the stack, as Laser has implicit output)
The flag is exactly as decoded. No curly brackets.
If a difference could difference differences from differences to calculate differences, would the difference differently difference differences to difference the difference from different differences differencing?
