Elements of a mutable data structure can be assigned to. For instance, the code
example = ['a', 'b']
example[0] = 'x'
example[1] = 'y'
changes the list example
from ['a', 'b']
first to ['x', 'b']
and then to
['x', 'y']
.
Fill in the placeholders so that the actual outputs match the expected outputs.
