Introduction
It is so surprise for me to read my own post over six months ago. There is a notification since one comment was added recently. I lost track on this algorithm on my github Leetcode repository page.
One algorithm with 4 upvotes
I was so surprised to learn that I got 4 upvotes on this algorithm. It is such good learning experience for me to learn to write a good post. I like to write the solution again when I have 10 - 15 minutes break.

1012. Numbers With Repeated Digits C# Study code from ranking No. 1 in weekly contest 128 (4 upvotes up to Oct. 8, 2019)
1012. Numbers With Repeated Digits C# standard depth first search with back tracking (1 upvotes up to Oct. 8, 2019)
Ranking board of discussion post
Here is the ranking based on number of upvote. It is a hard level algorithm. I wrote a post and then explained the top ranking weekly contest 128 No. 1, how his solution works and I wrote a C# solution with explanaton. Life is so interesting, I totally forgot what I did until some one left a comment on Oct. 8, 2019.
