AC still WA

@admin, In the question Chef and Cakes, when I submitted the solution, in the submission info, I got AC in (Sub-Task:1 and Task#:4), then why it is not counted as partially accepted, means some points, as it is showing totally wrong answer

this is not hackerrank/hackerearth, where you will get points for passing some test cases.
to partially solve a problem, your solution must correct answer all test cases in a sub-task.
