The backtracking method is a versatile algorithm used to solve various computational problems by progressively constructing potential solutions.
This code snippet is designed to solve sudoku puzzles: def is_valid(board, row, col, num): for i in range(9): if board[row][i] == num: return False for i in range(9): if board[i][col] == num: return False ...
While I understand that the optimal solution for this problem involves using dynamic programming, I decided to experiment with a bruteforce backtracking approach. In my approach, I subtract coins from the total amount and attempt to find combinations tha ...
