What is the output of the following program?for t in [4, 2, 3, 1][::-1]:  print (t)Options1 3 2 41 3 2 43 2 41324

Understanding the Program

The given program snippet is as follows:

for t in [4, 2, 3, 1][::-1]:  
    print(t)

1. The list [4, 2, 3, 1] is defined.
2. The slicing operation [::-1] reverses the list.
3. The for loop iterates through each element of the reversed list, outputting each number with the print function.

Step-by-Step Analysis

1. Original List: The original list is [4, 2, 3, 1].
2. Reversed List: When we reverse the list using [::-1], it becomes [1, 3, 2, 4].
3. Iteration and Output: The for loop will iterate over this reversed list, and print(t) will output each element on a new line.

Final Output

When the program runs, the output will be:

1
3
2
4

Conclusion

Therefore, the correct output consists of the numbers printed line by line, which would correspond to the option:
Final Answer: 1
3
2
4
