# Program to find largest product of three unique items in Python

Suppose we have a list of numbers called nums, we have to find the largest product of three unique elements.

So, if the input is like nums = [6, 1, 2, 4, -3, -4], then the output will be 72, as we can multiply (- 3) * (-4) * 6 = 72.

To solve this, we will follow these steps −

sort the list nums

n := size of nums

maxScore := -inf

maxScore := maximum of maxScore and (nums[0] * nums[1] * nums[n - 1])

maxScore := maximum of maxScore and (nums[n - 3] * nums[n - 2] * nums[n - 1])

return maxScore

## Example

Let us see the following implementation to get better understanding

def solve(nums): nums.sort() n = len(nums) maxScore = -10000 maxScore = max(maxScore, nums[0] * nums[1] * nums[n - 1]) maxScore = max(maxScore, nums[n - 3] * nums[n - 2] * nums[n - 1]) return maxScore nums = [6, 1, 2, 4, -3, -4] print(solve(nums))

## Input

[6, 1, 2, 4, -3, -4]

## Output

72
