WebNov 15, 2024 · Randomly insert new nodes into the tree until the total number of nodes is reached. The free edges are indicated in red. At each step, one free edge is chosen at random. A node is placed at that edge and this node adds two new free edges to the tree. This procedure does not generate a specific order of nodes.

WebThis is a simple program to create binary tree. We have added one element at a time. You can take the array of elements as input and create a binary tree from it. While solving programming questions, you need to traverse all the elements in the binary tree. There are different binary tree traversal algorithms you can use. Check this next.
