Filter/identify characters within a cell array

Say you have a cell array:
cell_array={'Kh','8h','8d','Kd','Ks'}
where h=hearts, d=diamonds, s=spades. In poker, the given combination would correspond to a full house (i.e. a pair and a set).
How do I identify a full house and not a set, a pair or two pairs?
As of now, I identify a set by searching for 3 identical values, e.g. three kings:
idKings=cellfun(@(x)any(ismember('K',x)),cell_array);
if sum(idKings)==3;
...
end
but how do I apply rules such that a full house is identified, and not a pair, a set or two pairs?

try this is code
value1 = cellfun(@(x)x(1),cell_array,'un',0);
[a,b,b] = unique(value1);
i1 = histc(b,1:max(b));
t = ismember(a,'K');
out = all(i1(t) == 3 & i1(~t) == 2);

Interesting. I havent thought about employing a histc. Thank you for the idea!
I thought that one could easily modify the "full house approach" to a simpiler case: two pair. However, it actually seems more difficult since one does not need to consider only 2 alike and 3 others alike, but rather 2 alike in two different pairs but also a third single value.
How does one identify these?
