A set groups unique elements of the same data type in sorted order. Inserting a new element modifies the set only if that element does not already exist in the set.
Element
Size—Number of elements in the set
Wires of set—Wire color matches the data type color of the element

Because a set maintains elements in sorted order, a set allows faster search, insertion, modification, and removal operations on the data than unordered data structures, such as arrays, even when the data size is large. A set has memory overhead to maintain the elements in sorted order, which arrays do not have.
