Description:

Instructions

Write a function that takes a single string (word) as argument. The function must return an ordered list containing the indexes of all capital letters in the string.

Example

Assert.AreEqual(Kata.Capitals("CodEWaRs"), new int[]{
       0,3,4,6});

 

using System;using System.Linq;public static class Kata{  public static int[] Capitals(string word)  {    //Write your code here    int[] array = new int[] { };            if (word == null || word == string.Empty)            {                return array;            }            string tmp = word.ToLower();            return Enumerable.Range(0, tmp.Length).Where(i => word[i] != tmp[i]).ToArray();  }}

 

 

其他人的解法：

值得学习的是char本身自带了判断是否大写字母的函数

using System.Collections.Generic;using System;public static class Kata{  public static int[] Capitals(string word)  {     var capitalIndexes = new List
     
      ();      for (var i = 0; i < word.Length; i++)      {        if (char.IsUpper(word[i]))          capitalIndexes.Add(i);      }      return capitalIndexes.ToArray();  }}
