Input

On the first line you, will receive how many people are waiting to get on the lift
On the second line, you will you will receive the current state of the lift separated by " ".

Output

When there is no more available space left on the lift, or there are no more people in the queue, you should print on the console the final state of the lift's wagons separated by " " and one of the following messages:

If there are no more people and the lift have empty spots you should print:

"The lift has empty spots!

{wagons separated by ' '}"

If there are still people on the queue and no more available space, you should print:

"There isn't enough space! {people} people in a queue!

{wagons separated by ' '}"

If the lift is full and there are no more people in the queue, you should print only the wagons separated by " "

Examples

Input	Output
15 0 0 0 0	The lift has empty spots! 4 4 4 3
Comment
First state - 4 0 0 0 -> 11 people left Second state – 4 4 0 0 -> 7 people left Third state – 4 4 4 0 -> 3 people left
Input	Output
20 0 2 0	There isn't enough space! 10 people in a queue! 4 4 4
Comment
First state - 4 2 0 -> 16 people left Second state – 4 4 0 -> 14 people left Third state – 4 4 4 -> 10 people left, but there’re no more waggons.

Input JS	Output
[ "15", "0 0 0 0 0" ]	The lift has empty spaces! 4 4 4 3 0
Comment
First state - 4 0 0 0 -> 11 people left Second state – 4 4 0 0 -> 7 people left Third state – 4 4 4 0 -> 3 people left
Input JS	Output
[ "20", "0 2 0" ]	There isn't enough space! 10 people in a queue! 4 4 4
Comment
First state - 4 2 0 -> 16 people left Second state – 4 4 0 -> 14 people left Third state – 4 4 4 -> 10 people left, but there’re no more waggons.

Made some changes to your code, hope this helps.

New code (100%):

using System;
using System.Linq;

namespace Program
{
class Program
{
static void Main(string[] args)
{
int waitingPeople = int.Parse(Console.ReadLine());

int[] currentState = Console.ReadLine()
.Split()
.Select(int.Parse)
.ToArray();

//int nondifference = 0;

int maxCapacity = 4;

bool noMorePeople = false;

for (int i = 0; i < currentState.Length; i++)
{
//if (currentState[i] >= 4)
//{
// currentState[i] = 4;
// waitingPeople -= currentState[i];

//}
//else if (currentState[i] == 0 || currentState[i] < 0)
//{
// int PreviousLeft;
// PreviousLeft = waitingPeople;
// if (PreviousLeft - 4 < 0)
// {
// currentState[i] = PreviousLeft;
// }
// else currentState[i] = 4;
// waitingPeople -= currentState[i];

//}
//else if (currentState[i] < 4)
//{
// waitingPeople -= currentState[i];
// currentState[i] = 4;
//}

int currentWagon = currentState[i];

if (waitingPeople - (maxCapacity - currentWagon) == 0)
{
waitingPeople -= maxCapacity - currentWagon;
currentState[i] = 4;
noMorePeople = true;
break;
}
else if (waitingPeople - (maxCapacity - currentWagon) < 0)
{
currentState[i] = waitingPeople;
waitingPeople = 0;
noMorePeople = true;
break;
}
else
{
waitingPeople -= maxCapacity - currentWagon;
currentState[i] = 4;
}
}

bool emptyCabins = false;

for (int i = 0; i < currentState.Length; i++)
{
if (currentState[i] < 4)
{
emptyCabins = true;
break;
}
}

if (noMorePeople == true && emptyCabins == true)
{
Console.WriteLine("The lift has empty spots!");
Console.WriteLine(String.Join(" ", currentState));

}
else if (waitingPeople > 0 && emptyCabins == false)
{
Console.WriteLine($"There isn't enough space! {waitingPeople} people in a queue!");
Console.WriteLine(String.Join(" ", currentState));
}
else if (waitingPeople == 0 && emptyCabins == false)
{
Console.WriteLine(String.Join(" ", currentState));
}
}
}
}
