Question
Predict the correct output for the given expression:
5 >> 2
and 5 << 2
?
Options
25
5
22
20
Solution
The correct output for the given expression: 5>>2 and 5<<2 is 1 and 20.
Here's the step by step explanation:
-
The '>>' operator is a bitwise right shift operator. It shifts the bits of the number to the right and fills 0 on voids left as a result. So, 5 (which is 101 in binary) >> 2 would give 1 (which is 1 in binary).
-
The '<<' operator is a bitwise left shift operator. It shifts the bits of the number to the left and fills 0 on voids left as a result. So, 5 (which is 101 in binary) << 2 would give 20 (which is 10100 in binary).
-
The 'and' operator would then compare the two results (1 and 20) and return the logical AND. Since both are non-zero, the result is True. But in Python, 'and' operator returns the last evaluated argument when the result is True. So, it returns 20.
So, the correct option is 1 and 20.
