First, the recursive equationAccording to the idea of divide and conquer, a recursive complexity can be written as a recursive equation.First, the solution of the recursive equation--guess and then proveThis method is also referred to as the surrogate method, the steps are as follows:1, the form of the Guess solution2. Mathematical inductive method proves correctExample:We assume that there is a recursive formula like this:We guess that the solution is T (n) =o (NLGN), and then the recursive sub

height of T is defined as the maximum value of its leaf node depth.Defines the distance between any two points A and B in the tree as the length of the shortest simple path. The diameter of T is defined as the maximum value of a bit of distance between the T.Enter a binary tree T, please calculate its height and diameter.InputEnter a total of three rows.The first line enters the value of N, which represents the total number of nodes in the tree.The first sequence traversal of the second behavio

The illustration above is a comparison between the Photoshop tutorial effect and the original picture Now we're going to start with the production of light-colored neutral tones (also called light coffee). First of all, we look at the main problems of raw materials: 1. There is no level of gray screen. 2. The complexion is suffused with red. Key points of knowledge Applied: 1. Calculate the black and white gray three selections with the calculation of PS. 2. Use hyperbola to strengthen shadow

Currently there are many image processing software, such as the United States Mito and other fool-like software, although easy to use, but the effect is far less than Photoshop. There are many features in Photoshop that can be used for later revision, even a very subtle change can have a significant impact on the final image results. In this PS tutorial, the author will be a number of adjustment layers, brushes, masks and other very basic PS tools to complete the portrait of the polishing. This
