Question: Question:
I have an array with a mixture of strings and numbers as elements. I want to sort all of this in numerical order, what should I do?
For example, if you have the following array:
["123", 200, "12", 85]
I want to sort this as follows.
["12", 85, "123", 200]
Answer: Answer:
You can sort by using the sort_by
method.
["123", 200, "12", 85].sort_by{|item| item.to_i} #=> ["12", 85, "123", 200]
It is the same even if you write as follows.
["123", 200, "12", 85].sort_by(&:to_i) #=> ["12", 85, "123", 200]
