Ruby中的CoderByte数组加法i-工作代码与非工作代码的区别

def array_addition_i(arr)
  max_num = arr.max
  arr.delete(max_num)

  (1..arr.length).each do |n|
    arr.combination(n).each do |comb|
      return true if comb.sum == max_num
    end
  end

  false
end

# 示例用法
puts array_addition_i([4, 6, 23, 10, 1, 3])  # 输出 true
puts array_addition_i([5, 7, 16, 1, 2])     # 输出 false

def add_arrays(arr1, arr2)
  result = []
  arr1.each_with_index do |num, index|
    result << num + arr2[index]
  end
  result
end

# 示例用法
puts add_arrays([1, 2, 3], [4, 5, 6])  # 输出 [5, 7, 9]
puts add_arrays([10, 20, 30], [40, 50, 60])  # 输出 [50, 70, 90]
