Description Jethro and Cletus are quarantined at home and bored. They spend most of their day sitting at their computer monitor working or browsing the internet in their small apartment. Out of boredom Jethro begins counting the number of steps needed to reach each location in their small apartment. After seeing that taking different paths from their computer to their coffee maker yields different numbers of steps a question dawns on them. They want to know what is the fewest number of steps needed to reach all of the locations in their small apartment starting from their computer. Fortunately, Jethro is quite skilled at ASCII art. So they model their room with ASCII characters. A space ' can be moved through. An asterisk '*' is a wall or furniture that cannot be traversed (no climbing over furniture!). Going up, down, left, right one space takes exactly one step (we'll assume no diagonal movements for that sake of simplicity). For example, here is a possible model of their room: Assume that (0,0) is the upper lefthand corner. For the sake of simplicity you can assume the apartment is enclosed in (*) characters and that the location of Jethro's computer has been marked with an 'A'. Jethro is still new to programming and wants to hire you to write the program to label all of the ' ' locations in their apartment with the minimum number of steps needed to reach them. To keep with the ASCII art theme you'll use the letters A-Z Such that: 'A' is 0 steps 'B' is 1 step ' C ' is 2 steps ' 'Y' is 24 steps ' Z ' is 25 (or more) steps Here's some example rooms: Example 1: Base room: Room after algorithm: AABCDGFE (We can't pass through the '*' symbols) Example 2: Base room: Room after algorithm: \begin{tabular}{llll} \multicolumn{3}{l}{} & \\ & A & & BABCDEFGHIJK \\ & & & CBCDFGHIJKL \\ & & & DCDEGHIJKLM \\ & & & EDHIJKLMN \\ & & & FEFGHIJKLMNO \\ & & & GFGHIOP \\ & & & HGHIJRQPQ \\ & \end{tabular} (We don't count past 'Z' since Jethro has a pretty small apartment) Part 1 - Programming: (15 points) Write a brute force recursive program to solve the problem described above in paintRoom.c. Hint 1: This program will take fewer lines of code than previous one but you'll need to think about and test them carefully. For reference, my recPaintRoom only had 10 lines of code in it. Hint 2: From any given space, you need to try to continue moving up, down, left, and right (i.e. 4 recursive calls). Hint 3: Your algorithm can move into a '*', but upon recognizing it as an obstacle, it should return from that call. Hint 4: It may help to track the distance traveled so far from the starting 'A' character. Hint 5: Only updating locations that contain a ' won't be enough. Sometimes you'll need to update a location you previously visited and labeled. Hint 6: chars can be treated like small valued integers. In particular, it may be helpful to use operations like ' + ' and '
