foldLeft

The foldLeft method is used to produce a single result by "folding" all the elements of a collection. The algorithm starts with a "zero" element which is paired with the first element of the collection to create an intermediate result element. Then that intermediate result is paired with the second element of the collection to create a new intermediate result, and so on, until the algorithm reaches the end of the collection. Then the final result is returned.
