The first element of preorder traversal is always root. We first construct the root. Then we find the index of first element which is greater than root. Let the index be ‘i’. The values between root and ‘i’ will be part of left subtree, and the values between ‘i+1’ and ‘n...
Im getting an error that from the main() - Class BST has no member named 'readFromFileData'/'searchForNode'/'deleteNode'/'printInorder'/'printPreorder' etc For the code posted just above, this is correct as the class BST now doesn't contain these functions. The original posted code di...
