Suppose you have a method that takes as its parameters two integer arrays data1 and data2 of the same length and it copies all the data from data1 to data2 and then clears data1 (that is, it sets all the values in data1 to 0). What would happen if someone invoked this method and passed in the same array for both arguments rather than passing in two distinct arrays?

Consider a list of full names formatted “firstname lastname”, like ["jules verne", "alexandre dumas", "maurice druon"]. write a list comprehension that produces a list with the full names in the format “lastname, firstname”. the resulting list should look like ['verne, jules', 'dumas, alexandre', 'druon, maurice']. the simplest solution may involve a nested comprehension: [ …. for … in [ … for … in … ]].
