Write the PYTHON programming to solve with breadth-first search and build node-arcs with python code for the attached problem:

3.25. Knight's tour problem. Consider the chessboard shown in Figure 3.13. Note that some
squares are shaded. We wish to determine a knight's tour, if one exists, that starts at
the square designated by s and, after visiting the minimum number of squares, ends at
the square designated by t. The tour must not visit any shaded square. Formułate this
problem as a reachability problem on an appropriately defined graph.
