how can sort array/vector repetition of elements? example input leo mike eric leo leo output _ _ _ or leo leo leo eric leo mike eric mike i recommend processing data in 3 passes: use std::sort repeated elements adjacent each other. iterate on sorted range recording length , position of each equal_range. now can resort sequence based on data you've recovered in step 2. may consider using stable_search in phase if secondary search key alphabetical.
