frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)
Explanation:
JFrame is the swing class that is used to display a frame object. The JFrame display contains an X button on the top right position which is used to turn off the display of the frame. However if we want to terminate the program on pressing the X button, we need to update the DefaultCloseOperation for the frame. JFrame provides a method ''setDefaultCloseOperation' for this purpose. When this method is called with the argument JFrame.EXIT_ON_CLOSE , it will cause the program to exit when the close button is pressed.
Answer:
Select "flight number", origin, destination, format(fl_orig_time, 'HH:mm' ) as "Departure Time", format(fl_dest_time, 'HH:mm') as "Arrival Time" from table_name order by flight_number

The script is used to select records from the table named 'table_name' and formatted to 24hr time format with the hour in capital letters (signifying 24 hrs). Then the inverted comma used for flight number is due to the space character ebtween the two words. In a select statement, order by comes after the table name. While as is used as an alias for a column in a table.
Answer:
O(log2N)
Explanation:
Whenever there is repeated division or split of a problem in two equally sized halves an there is no additional work means there no work other than splitting the problem the time complexity is O(log2N).
You can take the example of binary search.It is an algorithm based on divide and Conquer.It divides the array in two equal halves on each iteration and it's worst case time complexity is O(logN).
