Introduction 

It is most common question peer asks me in  mock interview. Have you seen the problem before? Sometimes I just answer quickly, similar problem. I like to practice one more time and see if there is an issue to work on and also get help from the peer. Today I found one in mock interview as well.

Analysis does not match code

Here is Deletion distance dynamic programming analysis and C# code. I asked the peer that the analysis does not match the code. And he confirmed with me after carefully review of my code and the analysis.

Nothing can beat the peer's insights.
