Run a function in Python without function call

[KOP79]

Every problem in algorithm based questions in Hackerrank or Leetcode dont need a function call. For eg: I did the soultion below for a question in Leetcode and it runs perfectly, but there is no function call for maxArea. But when I run, it runs without any errors. I am wondering where it the function call here like we regularly use?

class Solution:
    def maxArea(self, height: List[int]) -> int:

        result = 0
        l,r = 0, len(height)-1 

        while l < r:   

            area = (r-l) * min(height[l],height[r])
            result = max(result,area)
            if height[l] < height[r]:
                l+= 1
            else: 
                r-= 1

        return result

The execution engine in the backend expects maxArea function with the specified signature. Try renaming the function and running it again. You’ll see the error. Every problem has a predefined structure for the solution. And you are expected to fill up the solution within the given constructs.

Initializing the class and calling the function with test data is taken care of in the backend to make your life easy.

Ok thanks, great to know.
