题解 | 字符串最后一个单词的长度

using System;
using System.Linq;
using System.Collections.Generic;
public class Program {
    public static void Main() {
        string line;
        while ((line = System.Console.ReadLine ()) != null) { // 注意 while 处理多个 case
            
            string[] inputArr = line.Split();
  
            System.Console.WriteLine(inputArr.Last().Length);

        }
    }
}

This question is quickly resloved with C Sharp's strong tools help.Just one line input to process.And string[] is splited by the Sysytem.String's Split() method.You can use "string[]" to find the last string.length.So the question has been satisfactorily resloved here.
