如何添加一個數組的第一個元素到另一個數組的第一個元素

Question

我有波紋管[原文]兩個數組：

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

我想打印輸出如下：

full_name = ["prabhu chaitanya","raghu varma", "satish venkey"] 

Answer 1

你可以嘗試以下方法：

first_name.zip(second_name).map{ |x| x.join(' ')} 

Answer 2

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

Answer 3

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

或者：

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

Answer 4

你也可以試試這個：

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