Write a method count_between which takes three arguments as input: An Array of integers An integer lower bound An integer upper bound count_between should return the number of integers in the Array between the two bounds, including the bounds It should return 0 if the Array is empty. Some examples: count_between([1,2,3], 0, 100) # => 3 count_bet…

Count the numbers in an array between a given range

#1 first attempt
def count_between(array, lower_bound, upper_bound)
  count = 0
  array.each do |x|
    count += 1 if x >= lower_bound && x <= upper_bound
  end
  
  count
end

#2 second attempt
def count_between(array, lower_bound, upper_bound)
  between = array.select {|x| x >= lower_bound && x <= upper_bound}
  
  between.count
end

#3 third attempt
def count_between(array, lower_bound, upper_bound)
 array.select {|x| x >= lower_bound && x <= upper_bound}.count
end

#each attempt
