What are Linked Lists?
The data structure for grouping and storing similar items together in most programming languages is used as an array, also known as a list. An array is a linear data structure that stores items together contiguously in memory. A linked list is similar to an array in that it also is a linear data structure, however, linked list stores information non-contiguously in memory. Since arrays store information in a contiguous block of memory when creating and manipulating the array often times will result in having too much or too little memory allocated to it. Linked list is much better at memory utilization in that it stores information non-contiguously in memory and only uses memory when needed.
