[Ruby] Two Dimensional Translate

Write a method two_d_translate that takes in a 2 dimensional array and translates it into a 1 dimensional array. You can assume that the inner arrays always have 2 elements. See the examples.

def two_d_translate(arr)

end

arr_1 = [
  ['boot', 3],
  ['camp', 2],
  ['program', 0]
]

print two_d_translate(arr_1) # => [ 'boot', 'boot', 'boot', 'camp', 'camp' ]
puts

arr_2 = [
  ['red', 1],
  ['blue', 4]
]

print two_d_translate(arr_2) # => [ 'red', 'blue', 'blue', 'blue', 'blue' ]
puts

my code

def two_d_translate(arr)
	new_arr = []
  	
  	arr.each do |subArr|
      subArr[1].times {new_arr << subArr[0]}
    end
  
  	return new_arr
end

arr_1 = [
  ['boot', 3],
  ['camp', 2],
  ['program', 0]
]

print two_d_translate(arr_1) # => [ 'boot', 'boot', 'boot', 'camp', 'camp' ]
puts

arr_2 = [
  ['red', 1],
  ['blue', 4]
]

print two_d_translate(arr_2) # => [ 'red', 'blue', 'blue', 'blue', 'blue' ]
puts

solution

def two_d_translate(arr)
  new_arr = []

  arr.each do |subArray|
    ele = subArray[0]
    num = subArray[1]

    num.times { new_arr << ele }
  end

  return new_arr
end

arr_1 = [
  ['boot', 3],
  ['camp', 2],
  ['program', 0]
]

print two_d_translate(arr_1) # => [ 'boot', 'boot', 'boot', 'camp', 'camp' ]
puts

arr_2 = [
  ['red', 1],
  ['blue', 4]
]

print two_d_translate(arr_2) # => [ 'red', 'blue', 'blue', 'blue', 'blue' ]
puts
