findLargestRectangle

static com.mojang.datafixers.util.Pair<PortalUtil.IntBounds,Integer> findLargestRectangle(int[] heights)

Finds the largest rectangle within a histogram, where the vertical bars each have width 1 and height specified in heights.

参数:

heights - the heights of bars in the histogram

返回:

the base of the rectangle as an inclusive range and the height of the rectangle packed in a pair

Largest Rectangle in Histogram - LeetCode

Implementation Note:

This implementation solves the problem using a stack. The stack maintains a collection of height limits of rectangles that may grow as the array iteration continues. When a new height is encountered, each position p in the stack would be popped if the rectangle with height limit at position p can no longer extend right. The popped rectangle becomes the return value if it has a larger area than the current candidate.

When the rectangle area is calculated, the range is between p0 + 1, where p0 is the current top of stack after popping rectangles that can no longer extend, and the current iterated position i.
