Input: Each test case will start with a line containing two positive integers n m indicating the number of rows and columns in the grid. There will be a space between n and m. After this will come n rows of m strings indicating each card’s number and its orientation. (the first row is the top row and the first value in each row is the leftmost card.) Each string will be of the format OSV, where: O is the orientation: either ‘U’ for “face-Up”, or ‘F’ for “face-Down” S is the suit: one of ‘C’, ‘D’, ‘H’, ‘S’ for “Clubs”, “Diamonds”, “Hearts”, or “Spades”, respectively V is the face Value: one of ‘2’, … ‘9’, ‘T’ (ten), ‘J’ (Jack), ‘Q’ (queen), ‘K’ (King), or ‘A’ (Ace) Thus, “USA” indicates “Ace of spaces, face-up”, and “DC3” represents “3 of Clubs, face-down” You will have to (A) make sure that each OSV string is valid, and then (B) convert each to an integer in the range of -52 to +52, representing the four suits and 13 values, with the sign representing the orientation. Zero will not be used. If a string is not valid, your program must end. Immediately, with no error message (a rather user-unfriendly and heavy-handed way of handling errors, but this program isn’t necessarily about the input’s validity so much as it is about processing the stacks. Your input must accept upper- or lower-case characters(card identification strings are not case-sensitive). After these n rows there will be one more line containing n + m – 2 characters indicating the order in which to apply the flips to the grid. Each character will be either ‘T’, ‘B’, ‘L’ or ‘R’ corresponding to a top, bottom, left or right flip. All flip sequences will be legal, i.e., you won’t be asked to do more than n – 1 top and bottom flips or m – 1 left and right flips. You are not responsible for making sure that the flip directions are one of TBLR – I won’t test your code with an illegal flip direction. The maximum value for n and m is 20. A line containing two zeros will terminate input. Obviously, if m * n is > 52, it will require more than one deck of cards. Repeated cards should be a non-issue for your program

I needed a research summary to be rewritten according to the stylistic rules used in this college. Everything was done as I asked, I enjoyed the discount and will order again. Didn’t communicate with the writer.
