无形装逼最为致命，居然喜欢上用Linq了

using System;using System.Linq;public class Kata{  public string Pattern(int n)  {    // Happy Coding ^_^     string result = string.Empty;            if (n > 0)            {                result = string.Join(Environment.NewLine, Enumerable.Range(1, n).Select(item => string.Join(string.Empty, Enumerable.Repeat(item, item))));            }            return result;  }}
