| Name | Does | Sorted? |
|---|---|---|
| sort | orders items | No |
| find | first match | No |
| count | how many | No |
| binary_search | is it there? | Yes |
Remember
| Pass begin() and end() |
| Sort before binary_search |
Why loop by hand? These four do it. Four tools. Sort orders items. Find gives the first match. Count tells how many. Binary search needs sorted data. Remember two things. Pass begin and end. Sort before binary search.
