Rope data structure is a tree data structure which is used to store or manipulate large strings in a more efficient manner. It allows for operations like insertion, deletion, search and random access to be executed faster and much more efficiently in comparison to a traditional String.

More specifically a rope is a binary tree (that is, each node can have maximum of 2 children) where each leaf (end node) holds a string and a length (also known as a “weight”), and each node further up the tree holds the sum of the lengths of all the leaves in its left subtree. Nodes that are not leaf nodes do not hold an array of characters.
