FUNCTION productExceptSelf(nums):
n = length(nums)
CREATE array left of size n
CREATE array right of size n
CREATE array result of size n

// Build left array
left[0] = 1
FOR i FROM 1 TO n-1:
left[i] = left[i-1] * nums[i-1]

// Build right array
right[n-1] = 1
FOR i FROM n-2 DOWN TO 0:
right[i] = right[i+1] * nums[i+1]

// Build result using left and right
FOR i FROM 0 TO n-1:
result[i] = left[i] * right[i]

RETURN result

```
