Question

Consider the following the code segment that shuffles a deck of cards. the code so that the suits stay together. That is, shuffle the clubs, then shuffle the diamonds, then the hearts, and finally the spades. Therefore all the clubs are dealt first, then the diamond, etc. P = {[], [], []}: s = {'Clubs', 'Diamonds', 'Hearts', 'Spades'}: for c = 1: 52 card(c).suit = s{ceil(c/13)): card(c).val = mod(c, 13)+1: end x = 1: 52: for ii = 1: 100 c1 = randi ([1, 52)): c2 = randi ([1, 52]): t = x(c1): x(c1) x(c2): x(c2) = t: end for c = 1: 52 ii = mod (c, 4) + 1 p{ii} = [p{ii} card(x(c)))]: end

Explanation / Answer

p = {[],[],[],[]};

s = {'Clubs','Diamonds','Hearts','Spades'};

for c = 1:52

card(c).suit = s{ceil(c/13)};

card(c).val = mod(c,13)+1;

end

x=1:52;

for ii = 1:100

c1 = randi([1,13])

c2 = randi([1,13])

t = x(c1);

x(c1) = x(c2);

x(c2) = t;

c1 = randi([14,26])

c2 = randi([14,26])

t = x(c1);

x(c1) = x(c2);

x(c2) = t;

c1 = randi([27,39])

c2 = randi([27,39])

t = x(c1);

x(c1) = x(c2);

x(c2) = t;

c1 = randi([40,52])

c2 = randi([40,52])

t = x(c1);

x(c1) = x(c2);

x(c2) = t;

end

for c = 1:52

ii = ceil(c/13);

p{ii} = [p{ii} card(x(c))]

end
