The upper right corner number is greater than the number to be searched, define the left adjacent point as the upper right corner and re-judge the 3 cases.3. The upper right corner number is less than the number to find, define the bottom adjacent point is the upper right corner, re-judge the 3 cases.If the upper right corner is out of bounds, the description is not found.#include using namespaceStd;typedef

Shell: The shell is the most straightforward way to operate Linux, interacting with the Linux system through the input commands in the shell.The shell is a small box, each with a separate namespace, the login operation is a shell (possibly bash,zsh, etc.), each shell script is a shell, each shell variable name does not affect each other;~/.BASHRC,/ETC/BASHRC, etc. these are special shell, become shell configuration file, these files have alias (alias), export (variable output);These special file

Green tick: indicates that a newly checked-out working copy is overloaded with a green checkmark. Indicates that the subversion state is normal.Red exclamation mark: indicates that after you start editing a file, the state becomes modified, and the icon reload becomes a red exclamation point. In this way, you can easily see which files have been modified since you last updated your working copy and need to be submitted.Yellow exclamation point: indicates that a conflict icon becomes a yellow exc

The algorithm process is as follows:1) Random selection of K documents as centroid from N documents2) measure the distance to each centroid of each remaining document and return it to the class of the nearest centroid3) Recalculate the mass centroid of a given category4) Iterate through the new centroid to the original centroid equal to or less than the specified threshold, the algorithm endsAdvantages: 1. Fast and simple algorithm2. High efficiency and scalability for big data sets3. Time compl

Topic:Enter an array of integers to implement a function to adjust the order of the arrays in the array so that all the odd digits are in the first half of the array, and all the even digits are in the second half of the array.Solution One: O (n^2)Scan the array from the beginning, take out the number for each even number, and move all the numbers that are behind that number forward. After you have moved, there is an empty space at the end of the array, and the even number is placed in the empty

searched is definitely the last to be set to1the corresponding number. Of course, the final step is to verify that the number of occurrences is greater than half of the array.#include Solution Three: Based on the partition function, O (n)Basic idea:If the number of occurrences in the array exceeds half the length of the array, then the array is sorted, and the number in the middle of the array is the number that appears more than half. The time complexity of sorting an array is O (Nlog (n)), bu

Having understood the basic meaning of the component, we must further understand the meaning of the interface (interface). The interface describes the services that the component provides externally. Interfaces are interacted between components and components, between components, and between customers. So once a component is released, it can only provide a reasonable, consistent service through a predefined interface. The stability between this interface definition enables the client application
