Implementation of AVL Tree using graphics in C++. Since each element in a binary tree can have only 2 children, we typically name them the left and right child. It extends AbstractSet class and implements Set Interface in Java. The complete implementation of the segment tree includes the query and update functions in a lower number of lines of code than the previous recursive one. General operations performed using binary search: finding an element; lower_bound ; upper_bound; 1. binary_search: binary_search(start_ptr, end_ptr, num): This function returns true if the element is present in the container, else returns false. Right view of Binary Tree using Queue Time Complexity: O(N), Traversing the Tree having N nodes Auxiliary Space: O(N), Function Call stack space in the worst case.
