Recursively call for position (i+1, j) and (i, j+1).If destination is reached print the output matrix and return. Mark the position output as 1 and check if the current position is destination or not.if the position is out of the matrix or the position is not valid then return.Create a recursive function, which takes initial matrix, output matrix and position of rat (i, j).Create a solution matrix, initially filled with 0’s.If the path does not reach the destination then backtrack and try other paths. Solving one piece at a time, and removing those solutions that fail to satisfy the constraints of the problem at any point of time (by time, here, is referred to the time elapsed till reaching any level of the search tree) is the process of backtracking.Īpproach: Form a recursive function, which will follow a path and check if the path reaches the destination or not. Recommended: Please solve it on “ PRACTICE” first, before moving on to the solution.īacktracking Algorithm : Backtracking is an algorithmic-technique for solving problems recursively by trying to build a solution incrementally.
