03. Heart Delivery

Здравейте колеги,

Имам затруднения със споменатата задача, Пробвах какво ли не, но повече от 70/100 не става. Всички изходи разбира се са така, четох условието и съм направил всичко стъпка, по- стъпка. Видях някои други решения, които имат 100/100 и пак не успявам да открия защо моя код не работи.

И аз доста се въртях с тази задача. пробвай да броиш faild позициите на сърцата, а не колко са нулирани, да не би там нещо да се обърква.

int count =0;
for (int i = 0; i < neighborhood.length; i++) {
if(neighborhood[i] !=0) {
count++;
}
}
if(count==0){
System.out.println("Mission was successful.");
}else{
System.out.printf("Cupid has failed %d places.",count);
}

Everything was correct, just on line 38, you had to acutally print out the position on which Cupid is currently positioned and not the value of the selected house. For example, Cupid could be on index 2 and find a house that has 0 value, thus the output should be "Place 2 already had Valentine's day." and not "Place 0 already had Valentine's day."

Best,

using System;
using System.Linq;
using System.Collections.Generic;

namespace _03.HeartDelivery
{
class Program
{
static void Main(string[] args)
{
List<int> neededHearts = Console.ReadLine()
.Split("@")
.Select(int.Parse)
.ToList();

string input = Console.ReadLine();
int currentPossition = 0;

while (input != "Love!")
{
List<string> inputArg = input
.Split()
.ToList();

if (inputArg[0] == "Jump")
{
currentPossition += int.Parse(inputArg[1]);
}

if (currentPossition > neededHearts.Count - 1)
{
currentPossition = 0;
}

if (neededHearts[currentPossition] == 0)
{
// THIS IS WHAT CAUSED THE ERROR
//Console.WriteLine($"Place {neededHearts[currentPossition]} already had Valentine's day.");
Console.WriteLine($"Place {currentPossition} already had Valentine's day.");
}
else
{
neededHearts[currentPossition] -= 2;

if (neededHearts[currentPossition] == 0)
{
Console.WriteLine($"Place {currentPossition} has Valentine's day.");
}
}
input = Console.ReadLine();
}

Console.WriteLine($"Cupid's last position was {currentPossition}.");

int counter = neededHearts
.Count(h => h > 0);

//for (int i = 0; i < neededHearts.Count; i++)
//{
// if (neededHearts[i] == 0)
// {
// counter++;
// }
//}

//if (counter == neededHearts.Count)
if (neededHearts.Sum() == 0)
{
Console.WriteLine("Mission was successful.");
}
else
{
Console.WriteLine($"Cupid has failed {counter} places.");
}
}
}
}
