You are given a n x n 2D matrix representing an image.Rotate the image by degrees (clockwise).Follow up:Could do this in-place?In order to fulfill the follow up requirement, i.e. In-place, we should utilize a temporary int variable and switch the V Alues in the matrix. Coming back to our problem, rotating a matrix can is divided into steps and each step responses to rotating specific layer of the Matrix. For example, when n=6 there is N/2 = 3 steps from outside layers to inside layers. Public cl
This topic is still belong to the title of the search class, similar to the previous topic, the title of the request is given a target, in an ordered array to find the insertion order of the element, if present, return the element's subscript. This problem is more intuitive, so it is easier to do hands, it should be noted that the boundary conditions, such as:(1). The target element is smaller than the smallest element in the sorted array(2). The target element is larger than the largest element

In many of our frameworks or project applications, caching can improve the response speed of the program to a certain extent and reduce the load on the server. Therefore, we have considered introducing the cache module in some places, this article introduces how to use the open-source cache framework CacheManager to implement data caching. In the development framework, some common processing needs to be
Java record-48-linear Data StructureGenerally, data structures are divided into two categories: linear data structures and Non-linear data structures. Linear data structures include linear tables, stacks, queues, strings, arrays, and files. Non-linear data structures include: trees and graphs. Linear table: the logical structure of a linear table is a finite sequence of n data elements: (a1, a2, a3 ,... an) n is the length of a linear table (n> = 0).
