How to print nodes in ascending order in BST?
Initialize a Min Heap and a Max Heap to store the nodes in ascending and descending order of level and node values respectively. Perform a level order traversal on the given BST to store the nodes in the respective priority queues. Print all the nodes of each level one by one from the Min Heap followed by the Max Heap alternately.
How to print nodes in top level order?
Print all the nodes of each level one by one from the Min Heap followed by the Max Heap alternately. If any level in the Min Heap or Max Heap is found to be already printed, skip to the next level. Below is the implementation of the above approach:
How to get nodes in non decreasing order?
In case of binary search trees (BST), Inorder traversal gives nodes in non-decreasing order. To get nodes of BST in non-increasing order, a variation of Inorder traversal where Inorder traversal s reversed can be used. Algorithm Inorder (tree) 1. Traverse the left subtree, i.e., call Inorder (left-subtree) 2.
How to sort a list in ascending order in Java?
Algorithm Inorder (tree) 1. Traverse the left subtree, i.e., call Inorder (left-subtree) 2. Visit the root. 3. Traverse the right subtree, i.e., call Inorder (right-subtree) If the tree is not BST. You can create List and write the tree’s values into the list and sort the list in ascending order.
