Algorithm for tree traversal / traversing a tree






Algorithm:



Step1: Start

Step2: Assign 1 to root node
       Assign 2 to left subtree
       Assign 3 to right subtree
       Assign 4 to left of left subtree
       Assign 5 to right of left subtree

Step3: Perform printpreorder()
Step4: Perform printinorder()
Step5: Perform printpostorder()

Step6: print preorder function
       
       1.if node=null,then return
       2.Traverse the root node
       3.Traverse the left subtree
       4.Traverse the right subtree
     
      printinorder function

       1.if node=null,then return
       2.Traverse the left subtree
       3.Visit the root node
       4.Traverse the right subtree

      printpostorder function

       1.if node=null,then return
       2.Traverse the left subtree
       3.Traverse the right subtree
       4.Visit the root node

Step7:stop
