Nested Rectangle problem Description: there are n rectangles, each of which can be described by a A, a, long and wide. A rectangle x (A, b) can be nested in the rectangle y (c,d) when and only if ARujia said: The "nested" relationship between rectangles is a typical two-yuan relationship, and a two-dollar relationship can be modeled with graphs, which are nested

Then I drag the dialog box to find that the rectangle is still fixed at the position on the screen and cannot be dragged along with the dialog box, in addition, when another page overwrites the dialog box, the rectangle is drawn to another page, and the dialog box is minimized. The

I. Specific questions: Give a set of non-negative integers to represent a bar chart. design an algorithm to obtain the area of the largest rectangle in the bar chart. For example, enter the following data:, and. Each number indicates the height of a column. If the width of a column is 1 by default, the area of the maximum rectangle is 10. ==> This problem exists in leetcode: largest
