Well the first thing you need to do is compile and link their code. Once you have the executable code you can get information about its memory requirements by reading the executable header. Getting the time value is probably not possible as it depends on so many variables that will not necessarily be given with the program.

I have to ask why you are doing this project before you have figured out whether it is actually possible or not.
