//
// 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 even when 'other condition'
// is true and the loop is restarted by the 'continue' statement.
