Automatic Data Processing (ADP) Member Technical Interview Questions, Process, and Tips

Swapping two numbers without using a temporary variable.

• Use arithmetic operations to swap the values

• Add the two numbers and store the result in the first variable

• Subtract the second variable from the result and store it in the second variable

• Subtract the second variable from the first variable to get the original value of the second variable

• The values of the two variables are now swapped
