B. No, it only removes one element at a time C. Yes, by using a vector D. Yes, but only for specific types Show Answer 5. What is the time complexity of the 'erase' function for a set in C++? A. O(1) B. O(

Complexity Constant. Iterator validity All iterators, pointers and references remain valid, but now are referring to elements in the other container, and iterate in it. non-member overloads: operators (unordered_set) swap (unordered_set)
erase: Erase elements (public member function ) clear: Clear content (public member function) swap: Swap content (public member function) Buckets bucket_count: Return number of buckets (public member function) max_bucket_count: Return maximum number of buckets (public member function) ...

Complexity Constant. Iterator validity No changes. Data races The container is accessed (neither the const nor the non-const versions modify the container). Concurrently accessing the elements of asetis safe. Exception safety No-throw guarantee:this member function never throws exceptions. ...

Compared to aSmallVectorthat would never grow,FixedCapacityVectorwill be slightly more efficient (less checks) and make the intent clear, with nice additional iterator validity properties (begin()is never invalidated, iterators before any insert / erase are never invalidated). In addition, if type ...
Transformation operations are supported in all dup/cpy/cat functions, in order to both increase expressiveness and avoid unnecessary copies (e.g. tolower, erase, replace, etc.). E.g. you can both convert to lower a string in the same container, or copy/concatenate to another container. ...
