// EXERCISE: Fix the backing array problem
|
||
|
|
//
|
||
|
|
// You receive numbers from an API. After you're done working
|
||
|
|
// with it, the API needs to continue using those numbers.
|
||
|
|
//
|
||
|
|
// But your program changes the numbers (changes the API's slice).
|
||
|
|
//
|
||
|
|
// Fix the program so that your program doesn't modify
|
||
|
|
// the original numbers.

// RESTRICTION
|

|
|
//
|
||
|
|
// Fix your problem only in the designated area of the code below.
|
||
|

//
|
||
|
|
//
|
||
|
|
// EXPECTED OUTPUT
|
||
|
|
//
|
||
|
|
// Mine : [-50 -100 -150]
|
||
|
|
// Original nums: [56 89 15]
|
||
|
|
//
|
||
|
|
// Note: Original nums may vary (they're random)
|
||
|
|
// But your slice should look like the above (mine slice)
|
||
|
|
//
|
||
|
|
// Yes, it should output only three numbers for the both slices!
