Fermenta Biotech Quality Assurance Trainee Interview Questions and Answers

To reverse two numbers without using a temp variable, use bitwise XOR operation.

• Use bitwise XOR operation to swap two numbers without using a temp variable.

• Example: a = 5, b = 7. a = a XOR b, b = a XOR b, a = a XOR b. After this, a = 7, b = 5.
