What is a zig zag tree?

What is a zig zag tree?

ZigZag is a tree traversal algorithm that traverses the nodes in each level from left to right and then from right to left. The first level, which is just the root node, needs to be traversed from left to right. The next level is then traversed from right to left, i.e., 5, then 2, and so on.

What is zig zag level order traversal?

Given a binary tree, return the zigzag level order traversal of its nodes’ values. (i.e, from left to right, then right to left for the next level and alternate between).

How can you print leaf nodes of binary tree?

Printing leaf nodes of binary tree using Iteration

1. Create a Stack and push the root node.
2. loop until Stack is not empty.
3. Call Stack.pop() to get the last element and store its left and right child if they are not null.
4. if both left and right child of the last node is null then it’s a leaf node, print its value.

How do you care for a zig zag plant?

The zig zag plant is drought-tolerant but does best in moist soil with regular watering throughout the summer and hardly at all during the winter. In the spring and fall, water moderately. From spring to the middle of summer, add a liquid fertilizer when watering every three to four weeks.

How do you find all the leaf nodes in a tree?

Steps to find all leaf nodes in a binary tree in Java

1. If give tree node or root is null then return.
2. print the node if both right and left tree is null, that’s your leaf node.
3. repeat the process with both left and right subtree.

Is Zig Zag plant poisonous?

Symptoms: The sap is a skin irritant. Ingestion can cause vomiting and diarrhoea. Eye contact with sap is likely to cause pain and redness.

Is Zig Zag plant poisonous to cats?

This plant is so toxic that even the water in the collector bowl can become toxic. Within a few hours of eating the plant, your cat develops symptoms. If your cat doesn’t receive immediate veterinary treatment, signs of cardiac difficulty can appear if it ate enough of the plant.

How to do zig zag level order traversal?

If a NULL is encountered then check the direction to traverse the particular level is left to right or right to left. If it’s an even level then traverse from left to right otherwise traverse the tree in right to level order i.e., from the front to the previous front i.e., from the current NULL to to the last NULL that has been visited.

How to print Spiral order traversal of a tree?

Write a function to print spiral order traversal of a tree. For below tree, function should print 1, 2, 3, 4, 5, 6, 7. Recommended: Please try your approach on {IDE} first, before moving on to the solution.

How to print level Order of binary tree?

Start from the root node. Store it’s children in one stack. In every iteration, you have nodes of one level in one of the stacks. Print the nodes, and push nodes of next level in other stack. Repeat until your reach the final level. Time Complexity O (n) and space complexity O (n).
