Given an array of integers A of size N. A represents a histogram i.e A[i] denotes height of
the ith histogram’s bar. Width of each bar is 1.
Above is a histogram where width of each bar is 1, given height =
The largest rectangle is shown in the shaded area, which has area =
Find the area of largest rectangle in the histogram.
The only argument given is the integer array A.
Return the area of largest rectangle in the histogram.
Input 1: A = [2, 1, 5, 6, 2, 3] Output 1: 10 Explanation 1: The largest rectangle is shown in the shaded area, which has area = 10 unit.
