This article mainly explains "what is the knowledge of Java algorithm that needs to be mastered". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn what Java algorithm knowledge you need to master.

What is an algorithm?

In the Collins Dictionary, it is explained as follows:

An algorithm is a series of mathematical steps, especially in a computer program, which will give you the answer to a particular kind of problem or question.

In the computer, by the computer program (can be java, c, Python, etc.), through a series of mathematical steps, the way to solve a specific problem is the algorithm.

In vernacular understanding, an algorithm is the code that implements mathematical logic or mathematical formulas in a computer.

Knowledge to be mastered in learning algorithms

1. Any programming language, java, c, C++, Python, etc.

2. Data structure, such as array, linked list, tree, graph, etc.

3. Have a certain knowledge of mathematics. It doesn't matter if you forget the knowledge of mathematics. If the knowledge of mathematics in senior high school or above is involved in the article, you will also take everyone to review mathematics.

Connection and difference between algorithm and Mathematics

When we explain what an algorithm is above, we mention mathematics, so what is the relationship between mathematics and algorithms? Is algorithm equal to mathematics? With this doubt in mind, let's look at the following example.

1. An example of a primary school math problem:

Topic: please calculate 1 / 2 / 3 / 4 +. The sum of + N.

Mathematical formula: (1) N) * N ~ (2)

The above formula is a mathematical formula, we should have no objection. Because we saw such a math problem when we were studying math in primary school. So how can the same math problem be implemented in java code?

2. Java code implementation:

/ * *

* calculate 1-2-3 +... Sum of + 100

* @ param n

* @ return returns the sum

, /

Public static int algorithm (int n) {

Int sum=0

For (int I = 1; I
