// HINTS
|
|
//
|
|
// <<< BEWARE THE SPOILER! >>>
|
|
//
|
|
// I recommend you to first solve the exercise yourself before reading the
|
|
// following hint.
|
|
//
|
|
//
|
|
// + You can create a new array named alarm with the same length of the
|
|
// clocks array, so you can copy the alarm array to the clocks array
|
|
// every 10 seconds.
