Efficient Data Structures for Storing Partitions of Integers
... Here we proposed a tree structure to store all the partitions of an integer. The basic idea comes from an observation that two partitions of an integer may differ in only a few parts. For example, 〈1,1,1,1,1,1〉 and 〈1,1,1,1,2〉 differs in only two parts. In this situation, a sequence of the branches ...

Linked List data structure

It will require us to navigate to the previous element, starting from the beginning of the list as shown before. Removing an element from a singly-linked list has the same issue – i ...
