How can i join an array with from and to?

Time：01-27

I have an array, i would like to concat all less the first one element

for example

[1,2,3,4,5] the result should be 2345

i tried to do this but does not worked row.join("")

CodePudding user response：

Try these

[1,2,3,4,5].drop(1).join
=> "2345"

[1,2,3,4,5][1..-1].join
=> "2345"

CodePudding user response：

You can use:

yourList = [1,2,3,4,5]
yourList.shift
puts "#{yourList.join("")}\n\n"

OUTPUT: 2345
