Array updation in ruby

Given two arrays:

s1 = ["Arun#2#very good shop","Mani#4#i am very glad to meet you sir.","Anu#2#not bad"]
s2 = ["first","second","third"]

I want a new array s3 like:

s3 = ["Arun#2#very good shop#first","Mani#4#i am very glad to meet you sir#second.","Anu#2#not bad#third"]

Try this:

> s3 = [s1,s2].transpose.map{|a| a.join("#")}
 => ["Arun#2#very good shop#first", "Mani#4#i am very glad to meet you sir.#second", "Anu#2#not bad#third"]

Note: This will work if two array has same number of elements.

Alternative Option : this will work for any number of elements in two array

> s1.zip(["#"].cycle, s2).map(&:join)
 => ["Arun#2#very good shop#first", "Mani#4#i am very glad to meet you sir.#second", "Anu#2#not bad#third"]

s3 = s1.zip(s2).map{ |x| x.join('#')}
=> ["Arun#2#very good shop#first", "Mani#4#i am very glad to meet you sir.#second", "Anu#2#not bad#third"]

Assuming you want to append elements of s2 to s1 at corresponding index after #:

s3 = []
s1.each_with_index{|a, i| s3 << a + "#" + s2[i].to_s}
s3
# => ["Arun#2#very good shop#first", "Mani#4#i am very glad to meet you sir.#second", "Anu#2#not bad#third"]
