Halloween Candy Challenge

Question

import java.util.Scanner;
import java.lang.Math;

public class Program
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int houses = input.nextInt();
input.close();
double proba = (double)2 / houses;
double success = proba * 100;
System.out.println(Math.round(success));
//your code goes here

}
}
This is my java code to solve the Halloween candy task but I only pass the first two tests and am unable to pass the others I can't view.

Answer 1

Read the rounding requirement more closely:

"Output Format
A percentage value rounded up to the nearest whole number."

Your code is only rounding, not rounding up. There is a ceil() method for that.

Answer 2

Brian
For foreign citizens using a translator, this task is translated as follows:
— "Output format
The percentage value rounded to the nearest integer.",
which is what the round() method does...😎

I have been reporting this for many years, but they only argue with me in vain saying that I am wrong. And students make this mistake year after year and do not understand what they want from them...🤣🤣🤣

Answer 3

Thank you, Solo. I was unaware that there could be a translation failure. That does explain why so many struggle with this task. It is not always due to overlooking the requirement, but that the requirement is lost in translation! 👍✌️

Answer 4

Using the ceil() method worked but I had to convert my double number type to an integer. Thanks for the help.
