///************** BST QUESTION*************///////////// 
/// IN THIS QUESTION THEY WILL GIVE US A NUMBER AND IF IT IS PRESENT IN THAT TREE GIVE US TRUE OTHERWISE RETURN FALSE TO JUS 

/// APPROACH 
// if we get null return false otherwise if root->data > (number passed) go to the left side else go to right side 

///// FIRST APPROACH 
bool searchInBST(BinaryTreeNode<int> *root, int x){
    BinaryTreeNode<int> *temp = root;
    
    while(temp != NULL)
    
    if(temp->data == x){
        return true;
    }
    if(temp->data > x){
        temp = temp->left;
    }
    else{
        temp = temp->right;
    }
    return false;
}

////// second approach 
bool searchInBST(BinaryTreeNode<int> *root , int x ){
    // base case 
    if(root == Null){
        return false;
    }
    
    if(root ->data == x){
        return true;
    }
    if(root->data > x){
      return seachInBST(root->left , x ); 
    }
    else{
         return seachInBST(root->right, x ); 
    }
