Question
Choose the correct answer
What is the output of the following code snippet?
a = 0xFace
print(~a)
Options:
- 64207
- 64207
- 64208
- 64208
Solution
The output of the given code snippet will be -64208.
Here's the step by step explanation:
-
The variable 'a' is assigned a hexadecimal value 0xFace. In decimal, this value is 64206.
-
The tilde (~) operator is a unary operator in Python that does bit flipping. Bits that are 0 become 1, and the bits that are 1 become 0.
-
The binary representation of 64206 is 1111101011001110. After applying the tilde operator, we get 0000010100110001, which is the binary representation of -64207.
-
However, in Python, the tilde operator returns the negative of the number (n) subtracted by 1. So, the result of ~a is -(a+1). Therefore, ~64206 is -(64206+1) = -64207.
-
But in Python, the negative number representation is a two's complement representation. So, the actual output will be -64208.
So, the correct answer is -64208.
