WebApr 5, 2024 · Let's now examine how to determine a BST's height. The height is calculated by calculating the number of edges from the root node to the farthest leaf node. The root node is at height 0, and each additional edge adds one to the height. To calculate the height of a BST, start at the root node and traverse each branch until you reach a leaf node. WebBinary searching an array is a divide and conquer algorithm that takes an array and searches for a value in that array by splitting the array into halves. The algorithm works …

The worst-case time complexity is O(log N) . This means that as the number of values in a dataset increases, the performance time of the algorithm (the number of comparisons) increases as a function of the base-2 logarithm of the number of values. how common is the name orion
