//Description:
/*
 * This program takes a Sudoku puzzle solution as an input and then determines whether
 * the puzzle solution is valid. This validation is done using both single thread and 27 threads.
 * 27 threads are created as follows:
 * 9 for each 3x3 subsection, 9 for the 9 columns, and 9 for the 9 rows.
 * Each thread returns a integer value of 1 indicating that
 * the corresponding region in the puzzle they were responsible for is valid.
 * The program then waits for all threads to complete their execution and
 * checks if the return values of all the threads have been set to 1.
