Problem 53980. Determine whether a player solved a Cody problem

Created by ChrisR

Solve Later

Write a function to determine whether a player has solved the specified Cody problems. The problem numbers are specified as a vector, and the player names are specified either as a character vector for a single name or a cell array of character vectors for multiple names. Because some names are not unique, the player IDs are included as well. Return 1 if the player solved the problem, 0 if the player did not solve the problem, and -1 if the problem does not exist. If there are m players and n problems, the first output should be an  matrix. The second output should be a cell array of the problem titles.
I plan to check the tests regularly as players solve more problems. If you spot a problem, please feel free to contact me through my profile page.

Chris -- The correct y-matrices for tests 3 and 5 seem to have changed since this problem was written.

Thanks. I updated test 3. I'm seeing that test 5 still works.

Chris plz run my solution , as there are a bunch of issues with the test suite. In test 3 in particular : ['Guess the card in Fitch Cheney’s five-card trick'] . Am not sure as to why that matrix is there at all

Nikolaos, thanks for pointing out the extraneous brackets. They do not affect the tests, and the tests seem to work. I'll look through your code to see what's going on.
