有情有義生工人 7.13 In the card shuffling and dealing program of Fig 7.24, we intentionally used an inefficient shuffling algorithm that introduced the possibility of indefinte postponement. In this problem, you will create a high-performance shuffling algorithm that avoids indefinite postponement. Modify the program of Fig 7.24 as follows. Begin by initializing the deck array as shown in Fig 7.29. Modify the shuffle function to loop row-by-row and column-by-column through the array, touching every element once. Each element should be swapped with a ramdomly selected element of the array. Unshuffled deck array 0 1 2 3 4 5 6 7 8 9 10 11 12 0 1 2 3 4 5 6 7 8 9 10 11 12 13 1 14 15 16 17 18 19 20 21 22 23 24 25 26 2 27 28 29 30 31 32 33 34 35 36 37 38 39 3 40 41 42 43 44 45 46 47 48 49 50 51 52 Fig 7.24 是洗牌發牌程式，篇幅有點大，有需要我再貼。 --
