This article "how to achieve the sum of three numbers in java" is not quite understood by most people except programmers. Today, in order to make you have a better understanding of "how to achieve the sum of three numbers in java", I have summed up the following contents, which have a certain reference value. The detailed steps are clear and the details are handled properly. I hope you can get something through this article. Let's take a look at the specific content.

Given an array nums containing n integers, it is determined whether there are three elements in nums such that a + b + c = 0? Find all triples that meet the criteria and do not repeat.

Note: duplicate triples cannot be included in the answer.

For example, given the array nums = [- 1, 0, 1, 2,-1,-4], the set of triples that meet the requirements is: [- 1, 0, 1], [- 1,-1, 2]]

Parsing:

Note that the prefixes are compared. If the prefixes do not match, there is basically no need to compare later. In fact, it can be optimized. When the pre is empty, there is no need for comparison.

What are the basic data types of java? the basic data types of Java can be divided into: 1. Integer types, which are used to represent the data types of integers. 2.

Boolean type, which is the basic data type that represents logical values.

Thank you for your reading. I hope you have a certain understanding of the key issue of "how to achieve the sum of three numbers in java". The specific usage still needs to be understood through hands-on experiments. Try it quickly.
