dear I have this list  
@@spelers = Speler.new(‘Jan Janssens’, ‘M’, 5, ‘SR’),Speler.new(‘Leen  
Leniksen’, ‘V’, 7),  
Speler.new(‘Piet Pieters’, ‘M’, 3), Speler.new(‘Els Elsenbocht’,  
‘V’, 1, ‘J’),  
Speler.new(‘Karel Carlsen’, ‘M’, 8), Speler.new(‘Mieke Mieters’,  
‘V’, 9, ‘P’),  
Speler.new(‘John Johanses’, ‘M’, 5, ‘J’), Speler.new(‘Veerle  
Veldsen’, ‘V’, 3)

and I need to sort them into a top three for every mail and female in  
this list  
the M is for mail the V for female.

I have a def gender? geslacht  
@geslacht = geslacht  
end  
I know you could solve it like the example below however I would like to  
do it with an IF structure or with a bubble sort but not able to figure  
this out  
could someone help me out here and give me an example on how to solve  
this

def self.top3 geslacht  
per\_geslacht(geslacht).sort\_by { |x| x.score  
}.to\_a.slice(-3,3).reverse  
end

when it’s an if structure  
I should start somehow with  
if speler.score1 \> speler.score2  
print speler.score1  
else  
print speler.score2  
but after this I,m lost since I don’t know how to difference the first  
person from the second  
thanks for your help and feedback

Paul

Why? Is it slow? Does it not do exactly what you want?
