Procedure to delete all terminal nodes of the tree, Data Structure & Algorithms

Assignment Help:

Q. Let a binary tree 'T' be in memory. Write a procedure to delete all terminal nodes of the tree.      

Ans.

function to Delete Terminal Nodes from Binary Tree

void deleteleaves(struct node* root,struct node* prev)

{

 

if(root)

{

if(root->left==NULL&&root->right==NULL)

{

if(prev->item>=root->item)

prev->left=NULL;

else

prev->right=NULL;

printf("\n\n  %d Is Being Deleted ...",root->item);

free(root);

return;

}

deleteleaves(root->left,root);

deleteleaves(root->right,root);

}

}

the call to this function will deleteleaves (root, root).
