Solution
The output of the given Python code snippet will be:
0 1 2 2
Here's the step-by-step explanation:
-
The list
ct
is defined with four elements: 0, 1, 2, 3. -
The
for
loop starts. It takes the first element of the listct
(which is 0) and assigns it toct[0]
. This doesn't change the list becausect[0]
was already 0. It then printsct[0]
, which is 0. -
The
for
loop moves to the second element of the listct
(which is 1) and assigns it toct[0]
. Now the listct
becomes [1, 1, 2, 3]. It then printsct[0]
, which is now 1. -
The
for
loop moves to the third element of the listct
(which is now 2) and assigns it toct[0]
. Now the listct
becomes [2, 1, 2, 3]. It then printsct[0]
, which is now 2. -
The
for
loop moves to the fourth element of the listct
(which is 3) and assigns it toct[0]
. However, because the listct
has been modified during the loop, the fourth element is now 2, not 3. Soct[0]
becomes 2, and the listct
becomes [2, 1, 2, 3]. It then printsct[0]
, which is 2. -
The
for
loop has now finished all elements in the listct
, so it ends.
So, the correct option is "0122".
