Questions! See if you can answers!

See if you can answer these two questions.

1. You have a computer with 2 megabytes of ram and a file with 2 million 32-bit non-floating integers. How would you sort them. What problems might you run into? How do you do it in under 4 hours.

2. A system is using 100% of it's available memory, and you can't run any processes. If you kill a process, it comes right back. How do you troubleshoot the issue?

If you can answers I'll be surprised. I don't even know them
