    1. Kate is stuck in a maze. You should help her to find her way out.
    2. On the first line, you will be given how many rows there are in the maze. On the following n lines, you will be given the maze itself. Here is a legend for the maze:
    3. • "#" - means a wall; Kate cannot go through there
    4. • " " - means empty space; Kate can go through there
    5. • "k" - the initial position of Kate; start looking for a way out from there
    6. There are two options: Kate either gets out or not:
    7. • If Kate can get out, print the following:
    8. "Kate got out in {number_of_moves} moves".
    9. Note: If there are two or more ways out, she always chooses the longest one.
    10. • Otherwise, print: "Kate cannot get out".
    11.  
    12. Input
    13. 4
    14. ######
    15. ## k#
    16. ## ###
    17. ## ###
    18.  
    19. Output:
    20. Kate got out in 5 moves
    21.
