How can the solution from question 2 be integrated into the array $data[7]?

To integrate the solution from question 2 into the array $data[7], we need to assign the result of the solution to the desired index in the array. This can be done by simply assigning the result to $data[7]. This will update the value at index 7 in the $data array with the solution we obtained.

// Solution from question 2
$result = // your solution here;

// Integrate solution into $data[7]
$data[7] = $result;
