Given an arraylist of Strings, write a method that checks if any two strings in the arraylist when concatenated is identical to any other String in the arraylist. public void twoStringEquals(ArrayList arr) { } For example, if the arraylist has ["cat, dog, dot, ca, t, do,"t","g"], then the answer would be to print Yes, ca at location 3 and t at location 4 together form cat at location 0. Of course, there are other answers too, for instance, do and t form dot or do and g form dog. Any one answer is good enough. Concatenate operation is done by the usual + in Java. You can use get(..) or any other method to retrieve values from the ArrayList
