I've written a method that gets 3 arrays, in which the third one has to have all the numbers merged from the first two arrays. Then when I try to check if that works correctly it gives me that error.

```cs
        public static bool IsMerged(int[] arr, int[] brr, int[] crr)
        {
            int[] zrr = new int[999];
            int[] trr = new int[999];
            for (int i = 0; i < 1000; i++)
            {
                zrr[crr[i]]++;
                trr[arr[i]]++;
                trr[brr[i]]++;
            }

            for(int x = 0; x < 1000; x++)
            {
                if (trr[x] != zrr[x])
                    return false;
            }
            return true;
        }
```

```cs
int[] arr = new int[4];
            arr[0] = 2;
            arr[1] = 4;
            arr[2] = 7;
            arr[3] = 5;
            int[] brr = new int[3];
            brr[0] = 99;
            brr[1] = 4;
            brr[2] = 5;
            int[] crr = new int[7];
            crr[0] = 7;
            crr[1] = 4;
            crr[2] = 5;
            crr[3] = 5;
            crr[4] = 4;
            crr[5] = 2;
            crr[6] = 99;
            if (IsMerged(arr, brr, crr) == true)
                Console.WriteLine("IsMerged");
            else
                Console.WriteLine("IsNotMerged");
```

( It is known that there is up to numbers with three digits)

Easiest to $debug and check the values yourself

What are the limits to the loop? And is there a way to bypass that somehow?

and if let's say I make an array of a 1000

@phaseshift ```cs
        public static bool IsMerged(int[] arr, int[] brr, int[] crr)
        {
            if (crr.Length != arr.Length + brr.Length)
                return false;
            int[] zrr = new int[999];
            int[] trr = new int[999];
            for (int i = 0; i < crr.Length; i++)
            {
                zrr[crr[i]]++;
                trr[arr[i]]++;
                trr[brr[i]]++;
            }

            for(int x = 0; x < crr.Length; x++)
            {
                if (trr[x] != zrr[x])
                    return false;
            }
            return true;
        }
```

arr + brr length must be equal to crr length

Wait, if like let's say the int[] size is 5

Yes, of course. That's the point of the error
