Question

What does ~~~~~~5 evaluate to?

(a) +5

(b) -11

(c) +11

(d) -5

I had been asked this question by my school principal while I was bunking the class.

I need to ask this question from Numeric Types topic in division Variable Names, Operators, Data Types & Numeric Types of Python

Answer 1

The correct answer is (a) +5

Easiest explanation - ~x is equivalent to -(x+1).

~~x = – (-(x+1) + 1) = (x+1) – 1 = x

~~x is equivalent to x

Extrapolating further ~~~~~~x would be same as x in the final result.

In the question, x value is given as 5 and “~” is repeated 6 times. So, the correct answer for “~~~~~~5” is 5.
