Problem Description Many assignments for novice programmers involve card games. Central to the development of these games is the use of a virtual deck of playing cards that accurately emulates a real deck. A deck of playing cards is composed of 52 cards with thirteen ascending face values of 2, 3, 10, Jack, Queen, King and Ace, and four suites of Clubs, Spades, Diamonds and Hearts 13 faces x4suites 52 cards. To represent a card deck in our code, we will use an array of 52 integers, where the face value and the suite are encoded into the stored number and extracted using integer math. This can be done in two ways: (i) Assume our array counts from 0 to 51, and our interpretation is that this ascending set of numbers represents each face value in all four suites, followed by the next face value in all four suites, etc. Thus, we may obtain the face value by integer division of 4 and adding 2. The suite is obtained by arbitrarily assigning 0 to Clubs, 1 to Spades, 2 to Diamonds and 3 to Hearts. The suite is then found as the remainder when dividing by 4 (using the modulo operator) (ii) Assume our array assigns the 52 cards the following numbers with all aces being low: 0-12 (diamonds), 13-25 (hearts), 26-38 (clubs), and 39-51 (spades). So the ace of diamonds is assigned the value 0, the jack of clubs is assigned the value 36 etc. In this case, face and suite are determined via integer math using 13 divide by 13 for suite and modulus 13 to get face.Solution
