Question

Using MATLAB, please read question well

Function Name: stPaddysFeast Example search- Inputs 1 (struct) A MxN structure array 2. double) A 1x2 vector of your starting position: [row, column] next: [1, 3] next: [1, 1] next: [2, 1) food: 'potato food potato next: 2, 3] step 2 food: start next: [2, 2] food: 'potato' step 3 Outputs next [1, 21 food: food: 1. (ohar)A descriplion of how mary potatoes you found ad where you stopped looking step 4 (stop) Background Ho hum, what a day, you are just on your way back home after a bountful potato harvest when "KERSPLAT you trip on a misaligned cobblestone spilling your glorious potatoes over the side of the road into this magical maze. Your only hope is to turn to MATLAB in this trying time to help you gather up all your potatoes and even some corned beef from your local pub for your St. Paddy's Day Feast! found-stPaddysFeast (search, [1, 3]) found →·I found 2 potatoes before I reached the corned beef at position (2,2) Function Description: Notes: Given a structure array and a set of indices at which to start, move through the array to collect potatoes. Each structure in the array will contain the same two fields. next and food. The field called next contains a 1x2 vector with the indices of the next structure to look in. The foad field contains a char vector that either says patato, corned boof', or (empty char vector). You are guaranteed to reach the coned beef at some point Your path will not cross the same structure twice. Don't worry about grammar (saying 1 potatoes is okay). Start by looking in the structure at the index position given by the second input. If the food field of that structure says 'potato', add it to your basket (keep track of how many potatoes you find) Then, go to the structure at the indices contained in the next field. Continue following the path of indices and counting the number of potatoes you fine. If the focd field of a structure says 'corned beef' stop looking and output the current indices and number of potatoes collocted to the output. Format your output like this I found potatoes before I reached the corned beef at position (srow>,

Answer 1

function found = stPaddysFeast(search,ind)
i=0;
while ~(strcmp(search(ind(1),ind(2)).food,'corned beef'))
    if (strcmp(search(ind(1),ind(2)).food,'potato'))
        i=i+1;
    end
    ind=search(ind(1),ind(2)).next;
end
found=sprintf('I found %d potatoes before I reached the corned beef at position (%d,%d).',i,ind);
