## What is Sudoku Solver2?

The fun of Sudoku lies in the process of logical reasoning. In the current Sudoku application, when users encounter trouble, they either guess the digit by themselves or ask the system to help fill in an inexplicable digit. The biggest problem is that it cannot solve the user's confusion. The purpose of our Sudoku solver is to fill this gap.
