Analysis. Discussions. The class should have display() method, to print the width and height of the rectangle separated by space. For example: hist=[2,3,1,4,5,4,2] If you join KK adjacent buildings, they will form a solid rectangle of area K×min(hi,hi+1,…,hi+k−1)K×min(hi,hi+1,…,hi+k−1). 5 When you click submit, your code will be judged on multiple test cases which are hidden.

Hackerrank. A simple solution is to one by one consider all bars as starting points and calculate area of all rectangles starting with every bar. My solution the idea is same: area of rectangle include heights[i] is: (index of nextSmaller - index of previousSmaller - 1) * heights[i] So I first compute previousSmaller and nextSmaller, then the area is easy. Remember that this rectangle must be aligned at the common base line. We only need to keep track of the bars that are not blocked. My public HackerRank profile here.
