A binary search tree is a tree in which every node can have at most two child nodes. Considering any node $R$ with key $K$, nodes having key smaller than $K$ are in the left subtree rooted at $R$ whereas nodes having key larger than $K$ are in the right subtree rooted at $R$. Chef is fascinated by BSTs. Given an ordinary binary tree, he wonders what would be the inorder traversal of it were it
