A simple Baidu pen exam, a simple Baidu pen exam
I. Introduction

I tried to make a Baidu pen exam, which is quite interesting. I posted it to share it with you.

Ii. Question

When I get lazy, I won't repeat it and paste it directly. Haha.

3. My Solutions

First of all, let's consider the programming language. I am most familiar with java, so let's write it in java.

My idea: the input is grouped, the first is n, and the second is m. Therefore, this can be used as the principle of data separation. Read the Code:

for(int i=1;i<args.length;i+=2){double n=Double.parseDouble(args[i-1]);double m=Double.parseDouble((args[i]));getResult(n, m);}

After obtaining n and m, you can consider the algorithm. Let's talk about the Code:

public static void getResult(double n,double m){double result=0;while(m--!=0){result+=n;n=Math.sqrt(n);}System.out.printf("%.2f\n",result);}

Well, it's good. It's just a few simple lines of code that contain a lot of knowledge points. I have to say that there are still a lot of basic knowledge.

Configure running parameters:

Running result:

94.73

5. Last sentence

Have everyone gotten along with each other? I think someone has a better solution. I hope you can give me some advice on how to make common progress and grow together.
