// The last two exercises were functionally identical. Continue
// expressions really show their utility when used with 'continue'
// statements!
//
// Example:
//
// while (condition) : (continue expression){
//
// if(other condition) continue;
//
// }
//
// The "continue expression" executes every time the loop restarts
// whether the "continue" statement happens or not.
