From time to time, I like to check out some coding challenges online to see if I can muster up a solution to the problem.
Recently, I came across a practice problem where the goal was to determine if a sudoku board was valid or not. This was right up my alley as I love sudoku and a good challenge. These challenges can be an excellent resource for learning new skills and even for interview preparation. I’ll go over how to understand these problems, provide a solution with a detailed explanation, and conclude with some additional resources.
