angular interview question

The problem is very simple, but it is very meaningful, the last time I saw the powerful function of list, I think the question began to the Java API to consider, after all, not all the problems need to brains to think about the algorithm.For this personal implementation is as follows:/** merges data and sorts */public class Sortdemo {public static void main (string[] args) {listIf I put it in the past, I would definitely design a sort of sorting metho

design patterns you are familiar with? Have you ever brushed a leetcode? List the familiar Linux commands. What is the system on the company's online server? Explain the meaning of PV, UV? Explain the meaning of the QPS? The difference between Uwsgi and Wsgi? The role of supervisor? What is a reverse proxy? Describe the entire process of SSH. Any questions, go to those solutions? Is there a public number that focuses on what technical class? What new technology is being

Title Requirements:The Declaration of class cmystring is as follows:class cmystring{public: cmystring (char *pdata=NULL); CMyString (const cmystring str); ~cmystring (void); operator= (const cmystring str); Private : Char *m_pdata;};Implement the overloaded function of its assignment operator, which requires exception security, that is, if an exception occurs when an object is assigned, the state of the object cannot be changed.Reference sword refers to the 1th

Tags: include ABI this preparation NSIs Tom a little consistency ACLInterview these days, (during the interview, did not prepare anything, because recently very tired, brought a body past, basically did not take the brain)Well, we're pretty much on the technical side. Let me ask you one more question. A transaction in Oracle? You talk to me about business. I go, business, what do you want to know about busi

The front-end time goes out for an interview and has an interesting question: For each bucket of 9l and 11l, there is an unlimited amount of water. How can we get 10l of water? If you get such a question, let's talk about it first: 1) first fill the 11l bucket with full water and then fill the 9l bucket with the water in the 11l bucket, then we will get 2L of wat

Original address: https://www.cnblogs.com/faunjoe88/p/7992319.htmlMain content:1) put question: If two key through Hash%entry[].length to get the same index, will there be a risk of coverage?Here HashMap uses a concept of chained data structure. We mentioned above that there is a next property in the entry class that refers to the downward one entry.For example, the first key value to a comes in, by calculating the hash of its key to get the index=0,

When I returned from the interview, I found a very interesting question. It was actually not difficult to think about it. At that time, I took the exam and gave only the dumbest way, you can think about other methods. Question: Write a function in C language. When the input is 1, the output is 2. When the input is 2, the output is 1. At that time, I knew that th

It took me one afternoon to go to the interview yesterday and I was asked a lot of questions. The result was that I could not meet my treatment requirements and ended up. During this period, the Technical Director gave a question about the test logic. The question was as follows: nine of them looked like the same ball, but one of them was bigger than the other on

[Sword refers to Offer learning] [interview question 47: addition without subtraction, multiplication, division], sword refers to offer Question: To write a function and calculate the sum of two integers, The +,-, ×, and limit operators must not be used in the function.Solutions The binary value of 5 is 101, and the binary value of 17 is 10001. We still try to di

[Sword refers to Offer learning] [interview question 31: the largest sum of consecutive sub-arrays], sword refers to offerQuestion: enter an integer array with a positive or negative number in the array. One or more consecutive integers in the array form a sub-array. Returns the maximum value of the sum of all sub-arrays. The time complexity is O (n ). Example: For example, the input array is {1,-2, 3, 10,-

[Sword refers to Offer learning] [interview question 36: Reverse Order pairs in the array], sword refers to offer Question: two numbers in the array. If the first number is greater than the next number, the two numbers form a reverse order. Enter an array to find the total number of reverse pairs in this array.Example Analysis For example, in the array {7, 5, 6,

[Sword refers to Offer learning] [interview question 3: Search in two-dimensional array], sword refers to offer Question: In a two-dimensional array, each row is sorted in ascending order from left to right, and each column is sorted in ascending order from top to bottom. Complete a function, input a two-dimensional array and an integer to determine whether the a

[Classic Interview Questions] Maximum Product of sub-array, question Product Question Given an integer array of N length, only multiplication is allowed, division is not allowed, the maximum group in the product of any (N-1) number is calculated, and the time complexity of the algorithm is written. Train of Thought 1Exhaustion We find out a combination of all po

[Sword refers to Offer learning] [interview question 59: symmetric Binary Tree], sword refers to offer Question: implement a function to determine whether a binary tree is symmetric. If a binary tree is the same as its image, it is symmetric.Solutions We usually have three different binary tree traversal algorithms, namely pre-order traversal, middle-order traver

[Sword refers to Offer learning] [interview question 54: a string that represents a value], sword refers to offer Question: Use a function to determine whether a string represents a number (including an integer and a decimal number ).Example For example, strings "+ 100", "5e2", "-123", "3.1416", and "-1E-16" all represent numerical values, but "12e", "1a3. 14 ","

I recently attended the opportunity and went to the interview a few days ago, hitting the wall again. I did a total of four questions this time, and I was not able to provide a clear solution at that time. I just re-wrote one of the questions. Now I will share it with you. I hope you can help me find out if there are any better solutions. The question is probably like this: There are 0.1 million points in a
