The exam question says "this process is only allowed to have one page in main memory".

1. The program takes two pages. If a process can only have one page in memory, what does that imply?
2. Where in the program does the break between pages fall? What is the program doing on either side of the break?
3. Given the answers to (1) and (2), what does that mean for the efficiency of the program?
4. Given (3), where might you want the page break to fall?
5. How could you change where in the program the page break is?
