## Solution

You need to access the array from within the Formula Node. For example, you could use the following code in the Formula Node to access the array. Refer to the snippet below for an example of accessing an array in a Formula Node.

int32 i, j, n;
float64 x;
n = sizeOfDim(a, 0) - 1;
do {
i = 0;
for (j=0; j<n; j++)
if (a[j] > a[j+1]) {
x = a[j];
a[j] = a[j+1];
a[j+1] = x;
i = 1;
}
} while (i);
