在编写C#程序的时候,有时我们需要动态生成一些代码并执行.然而C#不像JavaScript有一个Eval函数,可以动态的执行代码.所有这些功能都要我们自己去完成.如下是实例. 动态创建代码: using System; using System.Data; using System.Configuration; using System.Text; using System.CodeDom.Compiler; using Microsoft.CSharp; using System.Reflec

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 histogram. Above is a histogram where width of each bar is 1, given height = [2,1,5,6,2,3]. The largest
Given a 2D binary matrix filled with 0's and 1's, find the largest rectangle containing only 1's and return its area. Example: Input: [ ["1","0","1","0","0"], ["1","0","1",&qu
