Проблем със задача Foot for Pets от Exam 28-29 March 2020

Здравейте колеги,

тази задача ми дава всички верни отговори на условията, обаче в judge ми дава 66/100 ?

Немога да разбера каде има проблем, не ми показва грешката от каде идва, като дебъгвам всичко се смята правилно.

Ето го и моя код:

package com.company;

import java.util.Scanner;

public class FoodForPets {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        double days = Integer.parseInt(scan.nextLine());
        double food = Double.parseDouble(scan.nextLine());

        double dogFood = 0;
        double sumDogFood = 0;

        double catFood = 0;
        double sumCatFood = 0;

        double biscuits = 0;
        double sumFood = 0;

        for (int i = 1; i <= days; i++){
            dogFood = Integer.parseInt(scan.nextLine());
            catFood = Integer.parseInt(scan.nextLine());
            sumDogFood = sumDogFood +dogFood;
            sumCatFood = sumCatFood +catFood;
            sumFood = sumFood+(dogFood+catFood);
            if (i == 3){
                biscuits = (dogFood+catFood)*0.1;
            }
        }
        sumDogFood = (sumDogFood/sumFood)*100;
        sumCatFood = (sumCatFood/sumFood)*100;
        sumFood = (sumFood/food)*100;

        System.out.printf("Total eaten biscuits: %.0fgr.%n",biscuits);
        System.out.printf("%.2f%% of the food has been eaten.%n", sumFood);
        System.out.printf("%.2f%% eaten from the dog.%n",sumDogFood);
        System.out.printf("%.2f%% eaten from the cat.%n",sumCatFood);
    }
}

При проверката на бисквитките трябва да не е само на третия ден както си го написал ти , а на всеки трети Трябва да е :

if (i % 3 == 0){

biscuits += (dogFood+catFood)*0.1;

}

Ето този код дава 100/100:

Нищо друго не съм променял :

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);

double days = Integer.parseInt(scan.nextLine());
double food = Double.parseDouble(scan.nextLine());

double dogFood = 0;
double sumDogFood = 0;

double catFood = 0;
double sumCatFood = 0;

double biscuits = 0;
double sumFood = 0;

for (int i = 1; i <= days; i++){
dogFood = Integer.parseInt(scan.nextLine());
catFood = Integer.parseInt(scan.nextLine());
sumDogFood = sumDogFood +dogFood;
sumCatFood = sumCatFood +catFood;
sumFood = sumFood+(dogFood+catFood);
if (i % 3 == 0){
biscuits += (dogFood+catFood)*0.1;
}
}
sumDogFood = (sumDogFood/sumFood)*100;
sumCatFood = (sumCatFood/sumFood)*100;
sumFood = (sumFood/food)*100;

System.out.printf("Total eaten biscuits: %.0fgr.%n",biscuits);
System.out.printf("%.2f%% of the food has been eaten.%n", sumFood);
System.out.printf("%.2f%% eaten from the dog.%n",sumDogFood);
System.out.printf("%.2f%% eaten from the cat.%n",sumCatFood);
}
}

Грешката ми беше, че не ги изчислявам за кратко направо на конзолата, а първо си ги бях направил на отделно променливите за накрая, от там нещо не съм го доискусурил и сега с твоята поправка стана.

Благодаря колега +1 :)
