C++ Standard Template Library in Practice - Sorting and Gathering - std::partition_copy

The video tutorial explains the standard partition copy function, which takes two input iterators, two output iterators, and a predicate. It copies elements from the input range to two different ranges based on the predicate's return value. The video provides an example using strings, demonstrating how elements are partitioned into 'true' and 'false' buckets without modifying the original string. The tutorial concludes with a preview of upcoming topics on searching and finding algorithms.
