Why is it when I write my code in workspaces, it's working perfectly, yet it wont work in the exam?

Why is it when I write my code in workspaces, it's working perfectly, yet when I add it in here it doesn't work and it counts the wrong number of Yay's. It says "I entered 5, but saw Yay! printed 6 times. "? I'm having trouble finding in the videos where this is even at, so I searched online. I've tried two different ways, each way giving me the same results. If I change the code even slightly at the while(n < i) line, it throws completely different random numbers.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
      static void Main()
        {

            bool keepGoing = true; 


            while (keepGoing)
            {
                Console.Write("Enter the number of times to print \"Yay!\": ");
                string entry = Console.ReadLine();
               if (entry == null)
               {
                 return;
               }

              if (entry.ToLower() == "quit")
                {
                    keepGoing = false;
                }

            else 
            {

                    try
                {
                  int n = 0;
                  int i = int.Parse(entry);
                  while(n < i)
                    {                                       
                       {
                           Console.WriteLine("Yay!");
                           n++;

                         }



                   }
            }

                catch(FormatException)
              {
                Console.WriteLine("That is not valid input.");
                continue;
              }             
            }   
      }
   }                                     
}
}

            while (keepGoing) {

                string entry = Console.ReadLine();

                if (entry.ToLower() == "quit") {
                    keepGoing = false;
                } else {
                    try {
                        int n = 0;
                        int i = int.Parse(entry);
                        while(n < i) {     
                            Console.WriteLine("Yay!");
                            n++;
                        }
                        keepGoing = false;
                    } catch(FormatException) {
                        Console.WriteLine("That is not valid input.");
                        continue;
                    }           
                }
            }  
        }   
    }
}

I added 'keepGoing = false;' after you printed 'yay' so the program would exit and not repeat. I would highly recommend watching your spacing, otherwise, it makes it extremely difficult to read your code.

Awesome! Thank you! That worked. I'll definitely work on my spacing as well.
