Canvas Reading Order
Asked at Figma· Screen
Reported by the problem's creator, not verified
You design a CanvasReader class that orders canvas elements the way a screen reader would read them. An element is [id, x, y]: id is its unique identifier, x grows to the right and y grows downward. Each test creates one CanvasReader() and calls its methods several times; every call's return value is recorded in order.
Examples
Example 1
Input: init =
[], operations =[["reading_order",[[[1,50,10],[2,10,10],[3,30,0],[4,0,20]]]],["reading_order",[[]]],["reading_order",[[[7,5,5]]]]]Output:
[[3,2,1,4],[],[7]]Explanation: Element 3 has the smallest y (0) and comes first. Elements 1 and 2 share y = 10, so 2 (smaller x) precedes 1, and 4 has the largest y. The empty call returns [], and the single element returns [7].
