Julia's practice:
C# language

Read other's submission:

1. C#, using Dictionary, HashSet - Speically helpful, when you are not sure what Latin chars are. You just declare in general Dictionary, HashSet.

2. C#, using List class, remove method:

3. C#, kind of functional programming, new style to Julia - like JavaScript programming style

4. using one array, first string each char - add to the array, second string each char - take away from the array, sum of abs value of each item.

5. Using IList interface, distinct method, and functional programming - Lambda Expression <- Julia, you should try this code by yourself. It should be quickly picked up.

6. Sort two strings first, and then, using two pointers - sliding forward

7. using string operation, remove a char from a string - for any char in both two strings
