// write a method called reverse() with an int array as a parameter
// The method should not return any value. The method can modify the array parameter

// In main() test the reverse() method and print the array both in reversed and non-reversed order

// To reverse an array, we need to swap the position of the elements
// For example, an array of {1 5 9 9 2} would become {2 9 9 5 1}
