Algorithm: Given n and m, find all stepping numbers in the range

Dec. 11, 2016

Introduction:
Julia start to have good time to read code review post. She started to check her post, no update; but quickly she started to look for good ones to read, and give out a few of upvotes. She earned 36 reputation, after she got more than 30 reputation, she can upvote/ downvote any post.

Here is the post she loves to read. The way she can support people's code review, is to give a upvote.

Workout:

Julia learns a few things through the code review. Will write down here.

Her favorite code review:

1. http://codereview.stackexchange.com/a/149157/123986

2. This one is better

http://codereview.stackexchange.com/a/149456/123986

Julia really likes the code review: Advanced topic, so she write the C# version,

She likes to share the code with comment, but she needs 50 reputation in order to post a comment.
So, Julia just wrote an answer for the question.

Actionable Items:

1. There are over hundreds programmers write good answers on stackExchange.com code review. Julia, work with them, try their ideas first using C# code, and then, try to improve, and enhance the work. Add code with some test cases, and question some variable names, and write down the ideas to make code more quick to follow.

2. Read more badges - what they are, how they are defined, come out filters to search, find most valuable posts.

    Badges - read, learn, memorize, and enjoy the searching using badges knowledge.
