Write a recursive function

double recSum(double array[], int count);
that takes an int argument and returns the sum of count array entries.

```
//Pre: Arguments are defined and initialized
//Post: return value is the sum of count array entries
double recSum(double array[], int count)
{
if (count == 0) return 0;
else
{
return recSum(array, count-1) + array[count-1];
}
}
```
