+// of two collections, producing a collection of the results.
+//
+// The method steps through the two input collections, applying function
+// resultSelector to corresponding elements of the two collections.
+// The method returns a collection of the values that are returned by resultSelector.
+// If the input collections do not have the same number of elements,
+// the method combines elements until it reaches the end of one of the collections.
+// For example, if one collection has three elements and the other one has four,
+// the result collection has only three elements.
