(C#) can anyone explain me what I did wrong?

Question

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int num = Convert.ToInt32(Console.ReadLine());

/*
1 - Easy
2 - Medium
3 - Hard
other - "Invalid option"
*/
switch(num)
{
case 1:
Console.WriteLine("Easy");
break;
case 2:
Console.WriteLine("Medium");
break;
case 3:
Console.WriteLine("Hard")
break;
default:
Console.WriteLine("Invalid option");
break;
}

}
}
}

I did it how I learned, and I don't know if I just have a typing error or if I'm just dumb
