一開始想標題還有點梗
當每天做重覆的事情時
想梗反而比解題還麻煩 XD

題目(Count characters in your string)：

5The main idea is to count all the occuring characters(UTF-8) in string. If you have string like this aba then the result should be { 'a': 2, 'b': 1 }
What if the string is empty ? Then the result should be empty object literal { }
For C#: Use a Dictionary<char, int> for this kata!
