Because of its complexity of O (LOGN), the binary algorithm has very high efficiency in the actual operation. The idea of binary algorithm is often combined with other algorithms to solve real project problems. For example, the nonlinear equation is

Now, suppose you have mastered the concept of staging area completely. What we're going to talk about here is why Git is better designed than other version control systems because git tracks and manages changes, not files.You will ask, what is the

Given a binary tree, determine if it is height-balanced.For this problem, a height-balanced binary tree was defined as a binary tree in which the depth of the Every node never differ by more than 1.Ideas:I've been stuck on this problem for one hours.
