To find the number of combinations possible for a set of objects, we need to use factorials (a shorthand way of writing n x n-1 x n-2 x ... x 1 e.g. 4! = 4 x 3 x 2 x 1). If you have a set of objects and you want to know how many different ways they can be lined up, simply find n!, the factorial of n where n is the number of objects. If there is a limit to the number of objects used, then find n!/(n-a)!, where n is the number of objects and n-a is n minus the number of objects you can use. For example, we have 10 objects but can only use 4 of them; in formula this looks like 10!/(10-4)! = 10!/6!. 10! is 10 x 9 x 8 x ... x 1 and 6! is 6 x 5 x ... x 1. This means that if we were to write out the factorials in full we would see that the 6! is cancelled out by part of the 10!, leaving just 10 x 9 x 8 x 7, which equals 5040 i.e. the number of combinations possible using only 4 objects from a set of 10.
If you go to Wikipedia and type "List of heads of state", you'll find a list of current heads of state (and heads of government, when they are not the same person). I'll leave it to you to check which of these qualify as "presidents".

All lists are linked lists; there is no such thing as a separate "sorted list". There are algorithms that can sort a list, of course, but they all work on linked lists.

One can find a list of C Compilers, along with helpful information at several online sites. Some of these online sites with this information are "Cplus" and "Delorie".
how mant 5-number combinations are there with tnumbers 1 thru 35, please list them all?
There are 56 of them and I am not inclined to list them all.
There are 3,262,623 combinations and I am not crazy enough to list them all.
I need to have listed all the 4 number combinations between 1 and 9
There are 32C3 = 32*31*30/(3*2*1) = 4960 combinations. I do not have the inclination to list them all.
Passwords are technically permutations, not combinations. There are 104 = 10000 of them and I regret that I do not have the time to list them. They are all the numbers from 0000 to 9999.

There are 52,360 of them and you must be joking if you think I have either the time or inclination to list them all.
