Question

Which option correctly sets the last value of the list to be the same as the first value?

List: [14,20,60,42]
Option 1: luckyNumbers[-1] = luckyNumbers[0]
Option 2: luckyNumbers[0] = luckyNumbers[-1]
Option 3: luckyNumbers[0] == luckyNumbers[-1]
Option 4: luckyNumbers[-1] == luckyNumbers[0]

Answer 1

The correct option to set the last value of a list to be the same as the first is Option 1: luckyNumbers[-1] = luckyNumbers[0].

Step-by-step explanation:

The question is referring to list manipulation in programming, more specifically how to set the last value of a list to be the same as the first value. Given the list: [14,20,60,42], the correct option to set the last value of the list to be the same as the first is Option 1: luckyNumbers[-1] = luckyNumbers[0]. This code assigns the first value of the list (luckyNumbers[0]) to the last position (luckyNumbers[-1]), effectively making them the same.

Option 2 would actually do the reverse, changing the first element to become the same as the last. Option 3 and Option 4 use the equality operator '==' which is used for comparison, not for assignment.
