Deletion of a Node from a Singly Linked List
Similar to insertion we have three cases for deleting a Node from a Singly Linked List.

• Deleting First Node in Singly Linked List
  
  To complete deletion of firstNode in the list we have to change Head pointing to Next of firstNode.
  
  Pseudocode:

  firstNode = Head
  
  Head = firstNode->Next
  
  free firstNode

  Complexity:
  Time Complexity: O(1)
  Space Complexity: O(1)
