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;
