lexicographical_compare
Syntax: #include <algorithm> bool lexicographical_compare( iterator start1, iterator end1, iterator start2, iterator end2 ); bool lexicographical_compare( iterator start1, iterator end1, iterator start2, iterator end2, BinPred p ); The lexicographical_compare() function returns true if the range of elements [start1,end1) is lexicographically less than the range of elements [start2,end2). If you're confused about what lexicographic means, it might help to know that dictionaries are ordered lexicographically. lexicographical_compare() runs in linear time. Related topics:
