- * Implement getTime function:
- *
- * Function takes string and returns first valid time in this string. Valid time
- * has format 'hh:mm'. Both hours and minutes have 2 digits, e.g. '09:00'. Hours
- * is at most 23 and minutes is at most 59. '37:98' is not valid time. If
- * correct time not found the function returns empty string.
- *
- * getTime('Breakfast at 09:00') === '09:00'
- * getTime('Breakfast at 09:60, Dinner at 21:00') === '21:00'
- * getTime('Breakfast at 09:59, Dinner at 21:00') === '09:59'
- *
- *
- * @param {string} str
- *
- * @returns {string} - valid time
