👉 In programming, a "codirect" is a type of data structure that allows for efficient insertion and removal of elements in O(1) time complexity. It's similar to a linked list but with an additional constraint - it can only contain one element at any given point. This makes it particularly useful when you want to insert or remove elements from the end of a list without having to traverse the entire list, as it allows for efficient insertion and deletion operations in constant time.
