我考了这题:

you have a 2D grid of ‘-1’ means a wall, a ‘’ means you can pass, a lowercase character means a door, and an uppercase character means the key of that respective.

Return the minimum steps to open all the doors. You cannot move back (I don’t remember to be hones) you just need to traverse the grid up, down, left, right and check if you can open all doors.
