So, feel free to experiment and play around with my code.Here’s the C++ code…#include using namespace std bool validity_check(int sudoku,int n,int p,int q) If you google for the Toughest Sudoku Puzzle out there, you’ll most likely be shown this puzzle…So I tried feeding this puzzle as the input grid in my code and here’s the solution that I got…Peace!Link to my GitHub Repository - When learning a language, why do we understand sentences we would not be able to make up by ourselves?īecause if the sentence is uttered in context, and you already know what most of the keywords mean, the number of possible solutions is limited.E.g. Note that in my code, a 0 in the sudoku grid array denotes a blank cell in the grid. In the main() function, you can edit the sudoku puzzle (line 88) to your desired sudoku problem. This process is repeated until you reach the exit of the maze.Sudoku ProblemGiven a partially filled grid of size 9 imes9, completely fill the grid with numbers between 1 and 9.A fully filled grid is a solution if:Each row has all numbers form 1 to 9.Each column has all numbers form 1 to 9.Each sub-grid (if any) has all numbers form 1 to 9.Sudoku puzzles are commonly found in local newspapers and are a good exercise for the brain if solved logically.Now, to demonstrate the Backtracking Algorithm, I have written a small code in C++ language. Now that you know which of the 3 paths leads to a dead end, you choose an alternative path and if you again reach a dead end, you backtrack. You walk for a while a while and you reach a dead end, you backtrack your way to get back to where the road split into 3. If the road ahead splits into let’s say 3 different paths, you start off by taking one path. Every time a path is tested, in case a solution is not found, the algorithm backtracks to test another possible path and this procedure is repeated until a valid solution is found or all paths have been tested.In a nutshell, this is analogous to finding your way out of a maze. The Backtracking Algorithm is a recursive algorithm that attempts to solve a given problem by testing all possible paths towards a solution until a valid solution is found.
