I’m trying to convert a String of numbers that are separated by
semicolons to an Array—totally for fun, to stretch my ruby
understanding, fyi.
I use the Array in a while loop which does work when the Array looks
like = [1,2,3,4,5,…]—so that part is working. But I want to use ruby
to
convert a String = “1;2;3;4;5;6;7;8;9;10” into an Array [1,2,3,4,5,…]
so
that I can use these values.
I’ve tried many a method, but can’t seem to get the desired result; I’ve
tried gsub(/;/, “,”), eval (), and others.
##########
raw_data = “1;2;3;4;5;6;7;8;9;10”
data = raw_data.split(/;/) #but this gives [“1”, “2”, “3”, “4”, “5”,
“6”, “7”, “8”, “9”, “10”], not [1, 2, 3,…]
#data = [1,2,3,4,5,6,7,8,9,10,11,12] # this is the desired result
boundary = 1
ending_boundary = 13
interval = (ending_boundary - boundary)/3
while boundary < ending_boundary
print "For the class #{boundary} to #{boundary + interval}, "
print "the group is: "
puts data.select{ |x| x >= boundary && x < (boundary + interval)
}.size
print data.select{ |x| x >= boundary && x < (boundary + interval)
}.join(’ ')
boundary = boundary + interval #increase the boundary to the next
class
print “.\n”
end
