Introduction
It is an easy level algorithm using dynamic programming solution. I stumbled on the solution a few times, I had to fix bugs three times in order to pass online judge.
The algorithm is my favorite one now. I know that the algorithm practice is also good training for me. Sometimes I notice that I need more training to understand the statement "the last character must be a one-bit character". I failed a few times since I did not memorize the requirement, I confused that the expression is valid to express the number.
My practice
I like to write something to share my practice. Here is Leetcode discuss link.
