Generic Pair

Create a generic Pair<A, B> class that holds two values of potentially different types. The class should have getFirst(), getSecond(), and a swap() method that returns a new Pair<B, A> with the values swapped.

Read two values from stdin (a string and an integer), create a Pair, swap it, and print both the original and swapped pairs.

Input

• Line 1: a string value (a single word with no spaces, 1 to 100 characters)
• Line 2: an integer value (any int value)

Output

• Line 1: (FIRST, SECOND), the original pair
• Line 2: (FIRST, SECOND), the swapped pair

Examples

Input:
hello
42

Output:
(hello, 42)
(42, hello)

Input:
Java
100

Output:
(Java, 100)
(100, Java)

Input:
world
0

Output:
(world, 0)
(0, world)

Input:
x
-5

Output:
(x, -5)
(-5, x)

Negative integers swap the same way as any other value.
