❔ I keep getting an error " Index was outside the bounds of the array"

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. $code

                Console.WriteLine("IsMerged");
            else
                Console.WriteLine("IsNotMerged");

int[] arr = new int[4];

Easiest to $debug and check the values yourself

But your loop is just too big

SStr1ke

1/29/2023

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

Pphaseshift

1/29/2023

Use the size of the arrays

SStr1ke

1/29/2023

and if let's say I make an array of a 1000 it will let me?

Pphaseshift

1/29/2023

Sure

I see, thank you! @phaseshift

        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;
        }

        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;
        }

I changed the code still the same error

Pphaseshift

1/29/2023

Time to engage brain a bit. Are crr, arr, brr all the same size?

SStr1ke

1/29/2023

arr + brr length must be equal to crr length Else it's false oh wait yeah nvm

Pphaseshift

1/29/2023

So you're looping over the size of crr

SStr1ke

1/29/2023

yes

Pphaseshift

1/29/2023

Doing crr[i]

SStr1ke

1/29/2023

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

Pphaseshift

1/29/2023

And brr[i]

SStr1ke

1/29/2023

and I loop till like 8 it will show error?

Pphaseshift

1/29/2023

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

SStr1ke

1/29/2023

Oh omg Thank you!
