+
+──────────────────────────────────────────────────
+
+Given an array of integers heights representing the histogram's bar
+height where the width of each bar is 1, return the area of the
+largest rectangle in the histogram.
+
+ 
+
+Example 1:
+
+Input: heights = [2,1,5,6,2,3]
+Output: 10
+Explanation: The above is a histogram where width of each bar is 1.
+The largest rectangle is shown in the red area, which has an area =
+10 units.
+
+Example 2:
+
+Input: heights = [2,4]
+Output: 4
