The maximum value is the answer. The m

GivenNNon-negative integers representing the histogram's Bar Height where the width of each bar is 1, find the area of largest rectangle in the histogram. Above is a histogram where width of each bar is 1, given height =[2,1,5,6,2,3]. The largest rectangle is shown in the shaded area, which has area =10Unit. For example, Given Height =[2,1,5,6,2,3], Return10. Idea: select the smallest value in the curren

Poj2559 Question: Find the largest rectangle in the Histogram , The input data is 7 2 1 4 5 1 3 3 7 is the number, and the histogram is as follows: Enumerate all rectangles with a width of 1 and expand them to the two sides to find the rectangle with its complete and largest area. If the k-th rectangle with a width of 1 is specified, the rectangle with a width of 1 can be expanded to the LK rectangle on

Leetcode Largest Rectangle in HistogramThis question is definitely a challenge. I had a lot of worship and thought for an hour. I went online for a night. After learning, we will share the following records. Specify a histogram to find the maximum area of the rectangle. Example: Given n non-negative integers representing the histogram's bar height where the width of each bar is 1, find the area of largest rectangle in the

A grayscale histogram is a gray-level function that represents the number of pixels in an image with a certain gray level, reflecting the occurrence frequency of a certain gray level in the image. If we regard the total pixel brightness (gray level) of an image as a random variable, its distribution reflects the statistical characteristics of the image, which can be characterized and described using the probability density function (PDF, it is display

The company recently gave me the task of using the ArcGIS API for Flex to show the pie chart directly on the map (business data) and the chart making of the histogram, rather than the click-to-point display of the Bubble window, which the company has implemented.After a period of groping, referring to some of the online resources, at present probably out, inside still need to improve the place.As follows:(1) Chart.mxml, the main display map of the eff

"Hist" is a short for "histogram (histogram, bar chart)".1.N = hist (Y)Bins the elements of Y into ten equally spaced containers and returns the number of elements in each Container. If Y is a matrix, hist works down the columns.(The elements of vector y are averaged into containers of 10 equal intervals, and the number of elements per container is returned.) If Y is a matrix, the hist directive operates on
