When we put those numbers in a binary search tree, we only need average(1 + 2 + 2 + 3 + 3 + 3 + 3) / 7 = 2.42 comparisons to find the number. The Binary Search Tree 's search algorithm is roughly O(log2n) However this is the best-case . Figure 2 Delete Node in a Binar...

The explanation above provides a rough description of the algorithm. For the implementation details, we'd need to be more precise. We will maintain a pair$L < R$such that$A_L \leq k < A_R$. Meaning that the active search interval is$[L, R)$. We use half-interval here instead of...

In Part 1, we looked at what data structures are, how their performance can be evaluated, and how these performance considerations play into choosing which data structure to utilize for a particular algorithm. In addition to reviewing the basics of data structures and their analysis, we also ...
