Write a backtracking algorithm that solves an arbitrary Sudoku puzzle.
Find the disjunctive normal form of each function and draw the combinatorial circuit corresponding to the disjunctive normal form. $$\begin{array}{cc|c}\hline x & y & f(x, y) \\\\\hline 1 & 1 & 1 \\\1 & 0 & 0 \\\0 & 1 & 1 \\\0 & 0 & 1 \\\\\hline\end{array}$$
The subset-sum problem is: Given a set \(\left\\{c_{1}, \ldots, c_{n}\right\\}\) of positive integers and a positive integer \(M,\) find all subsets \(\left\\{c_{k_{1}}, \ldots, c_{k_{j}}\right\\}\) of \(\left\\{c_{1}, \ldots, c_{n}\right\\}\) satisfying $$\sum_{i=1}^{j} c_{k_{i}}=M$$ Write a backtracking algorithm to solve the subset-sum problem.
The minimum-queens problem asks for the minimum number of queens that can attack all of the squares of an \(n \times n\) board (i.e., the minimum number of queens such that each row, column, and diagonal contains at least one queen). Write a backtracking algorithm that determines whether \(k\) queens can attack all squares of an \(n \times n\) board.
