Backtracking template below: public void backTracking { // GOAL(Here we need to check what do we want in the end) // SEARCH SPACE(Here we basically iterate through // every possible move from current position) // CONSTRAINT(Here we need to check // whether the above chosen move is valid or not)} With the above being said, solution below: I have collected and summarized general code templates for particular algorithms, and add most typical examples to help make better use of it.
