ruby - Splitting array and get desired elements -

-

If I have this array:

["1", "2", "3, one", "4, b"]

How can I get this array from it? 

  ["1", "2", "3", "4"]    
 
 
 It should also work ...  
  Array = ["1", "2", "3, a", "4, b"] i in 0 .. array.length () - 1 if array [i] .include? (",") Ab = array [i] .split (",") array [i] = ab [0] end-end print array # ["1", "2", "3", "4"] < / Code>

I do not think this is a relativant code. Can anyone tell me what should I do?
