std::multiset

While a std::set container prides itself on its exclusivity, std::multiset is a bit more accommodating. It still maintains order, but it allows multiple elements to have the same value. This container is like a club where members have ranks, but there’s room for more than one member at each rank.

Purpose and suitability

std::multiset is an associative container that stores sorted elements and allows multiple occurrences of an element. Its key strengths are as follows:

• Offering logarithmic time complexity for insertion, deletion, and search

It’s particularly suitable in the following scenarios:

• When duplicate values need to be retained
• When you require elements to always remain sorted
• When random access is not a necessity

Ideal use cases
