👉 Homeoidality is a concept in computer science and information theory that refers to the property of a data structure where all its elements are either all equal or all different. This property allows efficient computation of operations such as searching, sorting, and querying on these structures. For example, if we have a binary search tree (BST), where all nodes are either equal or all differ, then any operation that requires comparisons between the values of the nodes will be O(log n) in time complexity due to the
