Qus ~~~~~~5 का मूल्यांकन किससे होता है?
A. +5
B. -11
C. +11
D. -5
Solution
A. +5Explanation
The expression ~~~~~~5 evaluates to 5.
In Python, the ~ operator is the bitwise NOT operator, which inverts all the bits of its operand. When applied to an integer n, it computes -(n + 1).
Here's a step-by-step breakdown of the evaluation:
- ~5 evaluates to -(5 + 1), which is -6.
- ~~5 evaluates to ~~5. Since ~5 is -6, applying ~ again: ~-6 evaluates to -(-6 + 1), which is 5.
This pattern continues: each pair of ~ operators cancel each other out. Since there are an even number of ~ operators in ~~~~~~5 (six in total), they all cancel out, leaving the original number, which is 5.
