"Count the numbers in an array between a given range"

gistfile1.txt

def count_between(array, lower_bound, upper_bound)
  count = 0
  array.each do |num|
    if ((num >= lower_bound) && (num <= upper_bound))
      count += 1
    end
  end
  return count
end

Oh wow, you're really close. Instead of trying to get a count on the array, start a counter and after you array.each do I add += 1 with a conditional statement that it's within the range.

I went a different route though, I went with

array.select { |x| x <= upper_bound && x >= lower_bound }.size

ohhhh, you don't need the array.compact and array.count

all you need to put is count

def count_between(array, lower_bound, upper_bound)
count = 0
array.each do |num|
if ((num >= lower_bound) && (num <= higher_bound))
count += 1
eliminate the else part of the statement, it's understood that if it doesn't fulfill the if statement it doesn't do anything
end
return count
end
