These data structures are utilized by Graham scan algorithm for finding the convex hull of a set of points in O(n log n) ("big O of n-log-n") time. Backtracking algorithms like depth-first search utilize these data structures. They can be implemented as a singly-linked list with a pointer to the first element. In these structures the most recently added elements are also the first removed, so they
These data structures are utilized by Graham scan algorithm for finding the convex hull of a set of points in O(n log n) ("big O of n-log-n") time. Backtracking algorithms like depth-first search utilize these data structures. They can be implemented as a singly-linked list with a pointer to the first element. In these structures the most recently added elements are also the first removed, so they operate in a last-in first-out format. Infinite recursion can lead to their "overflow". For 10 points, name this data structure that is a collection of elements from which elements can be "pushed" and "popped."
