We simplyuse backtracking to generate all possible paths from the upper-left corner tothe lower-right corner and count the number of such paths. 1. Running time: 483483483seconds 2. Number of recursive calls: 767676billion See more If the path reaches the lower-right square before it has visited all othersquares of the grid, it is clear that it will not be possible to complete thesolution. … See more If the path touches a wall and can turn either left or right, the grid splitsinto two parts that contain unvisited squares. In this case, we cannot visit allsquares anymore, so we can terminate … See more If the path creates a dead end that is not the bottom left corner, either thepath will fail to visit all squares (the path may stop at the dead end or passover it, sealing a square off) or the … See more The idea of Optimization 2 can be generalized: if the path cannot continueforward but can turn either left or right, the grid splits into two parts thatboth contain unvisited squares.
