Mirror of Tree

February 10, 2015 by Dhaval Dave

Write a code to construct a Mirror of Binary Tree as below.

Solution 1 ) Create a New Tree and store nodes in the way we want (mirrored way)

Algo :

struct node{
    int value;
    struct node* left;
    struct node* right;
};
struct node *mirrorTree(struct node *root){
  struct node *temp;
  if(root==NULL)
    return(NULL);
  temp = (struct node *) malloc(sizeof(struct node));
  temp->value = root->value;
  temp->left  = mirrorTree(root->right);
  temp->right = mirrorTree(root->left);
  return(temp);
}
Solution 2 ) In place change ( Use Recursion )

 

void mirror(struct node* node) 
{
  if (node==NULL) 
    return;  
  else
  {
    struct node* temp;

    mirror(node->left);
    mirror(node->right);
 
    /* swap the pointers */
      temp        = node->left;
      node->left  = node->right;
      node->right = temp;
  }
}
