The basic operations that can be performed on a binary search tree data structure, are the following 1  â. Insert â Inserts an element in a tree/create a tree. 2  Search â Searches an element in a tree. 3  Preorder Traversal â Traverses a tree in a pre-order manner. 4  Inorder Traversal â Traverses a tree in an in-order manner.
1 Stack + max. 2  Create a data structure that efficiently supports the stack operations (pop and push) and also return the maximum element. 3  Assume the elements are integers or reals so that you can compare them. 4  Hint: use two stacks, one to store all of the elements and a second stack to store the maximums.
