I think the value of a repeated number can be found much easier: ``` long sum = 0; for (int i = 0; i < n; i++) { if(i < n - 1) { sum -= i; } sum += array[i]; }

printf("Element %d\r\n", sum); ```

This doesn't work if more than one value repeats itself.

I would really appreciate someone documenting exactly which variant of CRC32 is being used here.
