Program Plan Intro

Binary tree:

  • Binary tree is a non-linear data structure.
  • Binary tree contains node such as root node that is pointed to two child nodes.
  • A root node will have left reference node and right reference node.
  • Binary tree will contain more than one self referenced field.
  • Binary tree is similar to an upside down tree. Its structure is anchored at the top using a tree pointer that resembles the header pointer of the standard linked list.
  • The first node that is present in the tree is called as root node.
  • Every root node will have pointer to other nodes namely child nodes.
  • When a node does not contain any child node is called as leaf node.
