Find the maximum rectangle completely contained inside a histogram where each bars has a width of 1 unit. The heights of the bars of the histograms are given in an array e.g. {4,2,10,8,12,13,15,8,6} and they have a fixed width w = 1, say. The rectangles formed here are: 4X1, 2X9, 10X1, 8X6, 12X3, 13X2, 15X1, 8X6, 6X7 Thus, max-area rectangle = 8X6 = 48
