Singly Linked List

Singly Linked List is a variant of Linked List which allows only forward traversal of linked lists. This is a simple form yet it is effective for several problems such as Big Integer calculations. We will look into how various operations are performed and the advantages and disadvantages

String Algorithms

Z Algorithm function

The Z-function for a string S of length N is an array of length N where the i th element is equal to the greatest number of characters starting from the position i that coincide with the first characters of S.

suffix array

Suffix Array

A Suffix Array contains integers that represent the starting indices of all the suffixes of a given string, after the aforementioned suffixes have been sorted. There are two approaches to compute: O(N^2 * log N) and O(N * log N * log N) approach. Locate every occurrence of a pattern within a string

double ended queue

Double Ended Queue (Deque)

A double ended queue also called as deque (pronounced as ‘deck’ or ‘dequeue’) is a list in which the elements can be inserted or deleted at either end in constant time.
