Python/Python3

Code used for Submit/Run operation

area=0
        for i in range(len(points)-2):
            for j in range(i+1, len(points)-1):
                for k in range(j+1,len(points)):
                    s=abs(points[i][0]*(points[j][1]-points[k][1])+points[j][0]*(points[k][1]-points[i][1])+points[k][0]*(points[i][1]-points[j][1]))/2
                    if s>area:
                        area=s

oj-leetcode commented: Hello HazelY,

Thank you for bringing this issue to our attention.

It appears that your code might be facing issues related to floating-point precision when evaluated on different platforms. Please ensure your implementation adheres closely to the allowed precision (10^-5), and consider how small numerical differences can affect floating-point calculations differently across environments.

I would recommend adding debugging prints to understand any small differences the LeetCode platform might be catching. You might also want to cross-verify the computed area with some explicitly traced calculations to ensure the outputs are within the acceptable range.

For further suggestions, you might find the LeetCode Discuss forums helpful, as they are a great resource for community-based insights and potential similar cases.

We appreciate your understanding and patience.

Best regards,
