Question

I have an array (a nested array to be more precise), like this:

[["Armando", "P"], ["Dave", "S"], ["Richard", "R"], ["Michael", "S"], 
["Allen", "S"], ["Omer", "P"], ["David E.", "R"], ["Richard X.", "P"]]

I want to pass two tuples at a time as the parameters to another function, like:

rps_result(["Armando", "P"], ["Dave", "S"])
rps_result(["Richard", "R"], ["Michael", "S"])

I am trying do this as I loop through my array:

arr.each_slice(2) do |first, second|  
  rps_game_winner([first, second])
end

However, this does not give the desired answer when I print them the values of the arguments. What am I doing wrong here?

Answer 1

Just remove square brackets over arguments:

arr.each_slice(2) { |first, second| fun(first, second) }
