is this possible?

Question

on the way of solve some medium level question in java,i cant even find out the way to solve it,but.when i referred to the answer,i just realise :"Oh its the way! why i didn't think about it".
is this a problem?

Answer 1

Isn't learning something new such a wonderful experience? 😀

Sometimes our current abilities don't align with our current expectations, but that's okay. This can even be true for experienced programmers learning a new language or trying to accomplish something that isn't within their normal range of duties. For example, someone who might be used to encoding complicated math equations might suddenly be asked to manipulate strings and, as a result, find themselves going back to basics.

So in short, no, it's not a problem.

The more often you run across something, the more likely you will be able to recognize possible solutions and alternatives. People who don't have photographic memories (i.e. most people) require some form of repetition to build and strengthen synapses (neural pathways) generally via practice or some other means of review.

Keep up the good work! 👍🏻

Answer 2

Can I suggest that, before solving a small programming question set by others, try to apply what you have learned to develop some program of your own thoughts first?

Take for example, try doing the same thing with while loops, for loops and recursion.

After that, try making it a function,

after making a function, instead of displaying the result directly, make it return the result.

after making the function return its result, add parameter to the function to make it flexible.

Have you heard of a challenge called "Fizz Buzz"? It is good to begin and apply the above.

Answer 3

There are many ways to solve a problem. Just because you solved it using another method it doesn't mean your solution is wrong.

Nevertheless, it's better to solve the problem on your own first and then refer to another person's solution later.

If you really can't solve a problem on your own, you could take inspiration from someone else's solution and then implement your OWN version using their answer as a template. Remember, practice makes perfect.

It is a process.

You jump too quickly into "do exercise of solving problem".

You need to "play with" what you have learned first, to be familiar with each newly learned knowledge, otherwise when you face a problem, you don't know which to use. Same for Carmine 🇮🇹 .

I suggest beginning with something very very simple and develop it step by step and along the way, learn new things little by little.

If you know how David interviewed Morpheus, you can know how Fizz Buzz is suitable.

Please begin with trying to write a very simple program, which tests whether a number is divisible by 3.

Specification:

Input : 5 Output : No
Input : 9 Output : Yes

Begin with this, with language of your choice.

Post your code in comment to the following post :

And follow the page to do this series of tasks step by step to progress little by little.

Answer 5

Wang Teng Zheng No, telling a number is divisible or not is basic of basic, not deep at all.

If you show me your code, I can explain to you at where you get stuck.

You can ignore these and choose to learn at your own pace, of course.

Answer 6

Wang Teng Zheng
maybe it's deep now,
but not deep when you finish this series : https://www.sololearn.com/post/105678/?ref=app

Answer 7

Solve simple problems first and then move on to more complex ones.

You must learn to walk before you can run.

Answer 8

I have some question about JAVA script Have someone help me?

Answer 9

Gordon Which u prefer, do exercise of solving problem or practice like you said?

Answer 10

Gordon is it too deep? :D
i practise exercise in this site
https://www.w3resource.com/java-exercises/

Answer 11

Gordon no i mean is solving problem too deep? :D

Answer 12

Gordon check my profile the Rhombus structure code,i actually dont really understand it....i got this code from exercise

Answer 13

Gordon
import java.util.Scanner;
public class text{
public static void main(String[] args){
Scanner scanner = new Scanner(System.in);
System.out.println("Input a number");
int num = scanner.nextInt()

if(num % 3 == 0){
system.out.println("Yes");
}else{
system.out.println("No");
}
}
}

Answer 14

Be careful with the syntax, it should be System.out.println not system.out.println. Other than that, the solution is correct.

Answer 15

Lambda_Driver Okay,i just simply type it,cuz got shortcut in intelligent idea

Answer 16

Input:

5

2 2 1 3 1

2

Output:

1

Answer 17

James. zhan check inbox?

Answer 18

What can i do for anwser the question

Answer 19

I want to ask something. I don't have any knowledge about any programming language but I want to be Perfect at it. What should I have to do first?
