Smallest iteam using Link list

[ubarcomp]

Hi there;

if I have a link list and I want to get the smallest item. How to make that algorithm.

If the list is sorted, just pick either the tail or the head depending on how you sorted it.

If it's unsorted, you have to use a linear search (i.e. just go through each node and check).

this is the point:
how to check, using strcmp is enough or should I use any other way to get the smallest item.

note: the list is not sorted

Depends what's in the list. If you have a list of numbers, then this will work:std::list<int> blah;

// add numbers to blah

int x = std::min(blah.begin(), blah.end());How you decide whether another type of item is smallest is up to you.

What are you storing?
