The valid Sudoku problem involves verifying the entire 9x9 grid for a valid arrangement of numbers. Unlike solving the Sudoku grid, the goal here is to confirm whether the pre-filled values adhere to the Sudoku rules. The solution presented in the video is intuitive and employs a function to assess the validity of each cell, with a specific focus on pre-filled cells. This approach efficiently addresses the task by checking compliance with Sudoku game rules without the need for full grid resolution.
