A simple question can be directly simulated according to the question requirements. Note that the intermediate results can be saved to increase the running time by an order of magnitude.
There should be a faster method, but for the scale given in this question, thisAlgorithmThe results can be obtained quickly.

More than 100 typical JAVA interview questions and answer analysis (1)
This article will discuss various types of interview questions in Java interviews, which allow employers to test candidate's Java and general Object-Oriented Programming capabilities.
Object-Oriented Programming (OOP)
Java is a computer programming language that supports concurrency, class-based, and object-oriented. The advanta
Question: enter an integer to calculate the number of 1 in the Binary Expression of this integer. For example, input 10. Because the binary value is 1010 and there are two 1 s, Output 2.
Analysis: this is a basic examination bit operation interview question. Many companies, including Microsoft, have used this question.
The basic idea is to first judge whether the rightmost digit of an integer is
>=1; RET + = N;} return ret + 1 ;}
[Solution 2 of Question 2]
N! Contains the number of prime factor 2, which is equal to the number of 1 in the binary representation of N minus n. We can also solve this problem through this rule.
The following is an example of this rule. Suppose n = 11011, then n! The number of prime factor 2 is n/2 + N/4 + N/8 + N/16 +...

I. Question
Given the head pointer and a node pointer of the linked list, delete the node at O (1) time. The linked list node is defined as follows:Struct listnode
{
Int m_nkey;
Listnode * m_pnext;
};
The function declaration is as follows:Void deletenode (listnode * plisthead, listnode * ptobedeleted );
Ii. Analysis
This is a widely spread Google interview question. It can effectively evaluate our basic programming skills, our response speed, and mor

Enter an integer to calculate the number of 1 in the Binary Expression of this integer. For example, input 10. Because the binary value is 1010 and there are two 1 s, Output 2.
This question is very simple. It is a bit operation. We can shift one bit to the left and judge whether the last bit is 1. Not much,CodeAs follows:

Description
Xiaonan has learned binary. He wants to know the number of 1 in the Binary Expression of a number. Can you help him write a program to complete this task?
Input
Enter an integer N in the first line, indicating the number of groups of test data
Definition of prime number:
Refers to the number of natural numbers greater than 1 that cannot be divisible by other natural numbers except 1 and the integer itself.
1 and 0 are not prime or composite. Prime numbers are two concepts that are relative to composite, and they form one of the most fundamental definitions of number theory.
