Hi,

I have problem when i get an array using I get "Array Index Out of Bound" in QuickS function

```
getArray(int [] arr)
for (i = 0; i < arr.Length; i++)
{
String val = Console.ReadLine();
arr[i] = Convert.ToInt32(val);
}
public static void quicks(int lo, int hi, int[] arr)
{
int i = lo;
hi = arr.Length;
int j = hi;
int pivot;
pivot = arr[(lo + hi) / 2];
if (lo >= hi)
{
return;
}
Console.WriteLine(pivot);
do
{
while (arr[i] < pivot)
i++;
while (arr[j] > pivot) // when it comes here it says Array
// out of bound problem
j--;
if (i < j)
{
int temp = a[i];
a[i] = a[j];
a[j] = temp;
}
} while(i < j ); // end of do condition
if (lo < j) quicks(lo, j,arr);
if (i < hi) quicks(i, hi,arr);
```

Please help me in correcting quicksort function
