The algorithm uses prefix and suffix products: Compute prefix[i] = product of all elements before index Compute suffix[i] = product of all elements after index result[i] = prefix[i] × suffix[i] For [, , , ]: - prefix = [, , , ] (products before each index) - suffix = [, , , ] (products after each index) - result = [, , , ]
