Witryna15 cze 2024 · C++ maps are efficient data structures even for insertion just because the underlying data structure (a red black tree) ‘balances’ itself after every operation if required. Remember the list data structure you created for changelog? Assume the “many moons ago” version was a beta version and I would like you to mark it as such. WitrynaThe Map Container is one of many C++ containers that are used to store data. Moreover, Map belongs to the sub-branch of Associative containers, which store data in a sorted order. This makes accessing and searching through the data faster, and the cost of inserting data taking longer. Creating a Map Container
