More generally, attempting an How to use a word that (literally) drives some pe Editor Emily Brewster clarifies the difference. Splits the elements of a sequence into chunks of size at most size. If the list fits in the specified array with room to spare (i.e., That means a list element of a List object does not have to be boxed before the element can be used, and after about 500 list elements are created, the memory saved by not boxing list elements is greater than the memory used to generate the class implementation. a record of short pieces of information, such as people's names, usually written or printed with a single thing on each line and often ordered in a way that makes Invokes a transform function on each element of a sequence and returns the minimum Double value. specified collection is this list, and it's nonempty.
