Introduction
Flowchart to swap two numbers without using any other variables. Normally, during a swap operation, we tend to use a temp variable to hold one value. In this tutorial, we will design a flowchart to swap numbers without using a temporary variable.
Sample output
x=32
y=85
After swap
x=85
y=32
