이진 탐색 트리를 사용하여 배열의 최대 요소를 찾는 C++ 프로그램입니다. 이 프로그램의 시간 복잡도는 O(log(n))입니다.
알고리즘
Begin Construct the Binary Search Tree using the given data elements. Next traverse the root pointer to the rightmost child node available. Print the data part of the node as the maximum data element of the given data set. Print the Depth of the maximum data. End

출력
Data set: 86 63 95 6 7 67 52 26 45 98 The maximum element of the given data set is 98 data found at 2 depth from the root.
