+# Day 47 - Implement a singly linked list
+
+Write a program to implement a singly linked list
+
+### Linked Lists
+
+#### Source: [GeeksForGeeks](https://www.geeksforgeeks.org/data-structures/linked-list/)
+
+A linked list is a linear data structure, in which the elements are not stored at contiguous memory locations. The elements in a linked list are linked using pointers
+
+### Advantages of Linked Lists
+
+1. Dynamic size
+2. Ease of insertion/deletion
+
+### Disadvantages of Linked Lists
+
+1. A middle element can't be accessed directly, only traversal is possible
+2. Extra memory space for a pointer is required with each element of the list
