如何将数组的第一个元素添加到另一个数组的第一个元素

Question

我有两个阵列的波纹管[sic]：

address

我想打印以下输出：

first_name = ["prabhu" ,"raghu" , "satish"]
second_name = ["chaitanya", "varma", "venkey"]

Answer 1

您可以尝试以下操作：

{{1}}

Answer 2

[first_name, second_name].transpose.map{|a| a.join(" ")}

Answer 3

你也可以试试这个：

full_name = [];
first_name.each_with_index {|x, i|  x + second_name[i]}

Answer 4

first_name.zip(second_name).map { |f, l| "#{f} #{l}" }
=> ["prabhu chaitanya", "raghu varma", "satish venkey"]

可替换地：

first_name.zip([" "].cycle, second_name).map(&:join)
=> ["prabhu chaitanya", "raghu varma", "satish venkey"]
