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; } }
