// EXERCISE: Fix the backing array problem
//
// Ensure that changing the elements of the `mine` slice
// does not change the elements of the `nums` slice.
//
//
// CURRENT OUTPUT (INCORRECT)
//
// Mine : [-50 -100 -150 25 30 50]
// Original nums: [-50 -100 -150]
//
//
// EXPECTED OUTPUT
//
// Mine : [-50 -100 -150]
// Original nums: [56 89 15]
//

// DON'T TOUCH THE FOLLOWING CODE

// ----------------------------------------
// ONLY ADD YOUR CODE HERE
//
// Ensure that nums slice never changes even though
// the mine slice changes.

// ----------------------------------------
// DON'T TOUCH THE FOLLOWING CODE

// This code changes the elements of the nums
// slice.
