Question

Write a function that takes an array, loops over the indices, multiplies together all array values and returns the result.

Question

⚠ Advanced exercise ⚠

Run the following macro and write down the final result. Then refactor the code into one or several functions to avoid code duplication.

Macro with duplication
array1 = newArray(1, 34, 6, 21, 84, 14, 8);
array2 = newArray(54, 24, 67, 28, 42, 2, 17);

sum_array1 = 0
for (i = 0; i < array1.length; i++) {
    sum_array1 += array1[i];
}
mean_array1 = sum_array1 / array1.length;
ratio = sum_array1 * sum_array1 / mean_array1;

sum_array2 = 0
for (i = 0; i < array2.length; i++) {
    sum_array2 += array2[i];
}
mean_array2 = sum_array2 / array2.length;
ratio /= sum_array2 * sum_array2 / mean_array2;

// It should print 0.7179
print("Ratio: "+ratio);
