points with the largest slope must be adjacent, so two more two can be judged again.6. Ordered array to find more than half of the number. If you don't know if there's more than half, how to judge. What if the judgment is over 1/3?The median number. Use the median lowerbound and upperbound to judge. Judged by the upper and lower bounds of the number 1/3 and 2/3 positions.7.

After a recent interview with a company, I was asked two questions about algorithms: 1. Maximum child segment sum (a classic Dynamic Programming Algorithm) 2. If the data type stack is known, implement the queue. The Code is as follows: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Using System;Using System.

Start searching from the top right corner, the current element map[x][y] and the number of n to be searched can be as follows: Map[x][y]==n--Returns TrueMap[x][y]>n---Move leftMap[x][y] Search Process Examples: AC Code: ImportJava.util.Scanner; Public classMain { Public Static voidMain (string[] args) {Scanner sc=NewScanner (system.in); intn=Sc.nextint (); intm=Sc.nextint (); intk=Sc.nextint (); intx[][]=New int[N][m]; for(inti=0;i){ for(intj=0;j) {X[i][j]=Sc.nextint (); }

Analysis:Large numbers can be too large to be stored in the shaping type. It is necessary to use other algorithms to complete the multiplication operation.You can use the steps of the mental arithmetic multiplication to simulate multiplication operations. For example, the following:123* 122=3 4 6+ 3 4 6+ 1 2 3= 1 5 0 0 6Implementations such as the following:#include The results of the execution are as follows:./test122*123=15006./test 999 888999*888=887112 49.

---restore content starts---Dynamic programming is the number of the longest ascending sequence (longestincreasingsubsequence) in an array, with the complexity of O (n^2).For example: Array int arr[] = {7,3,5,9,4,6,8,10}, the longest ascending sequence should be 3,5,6,8,10 or 3,4,6,8,10, the final answer should be 5;Dp[i] Represents the number of the longest ascending sequence at the end of the following Mark I in the array, then the original problem is converted in order to find the maximum val
