SpletIn computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory.For example, in a program, two variables may be defined thus (in pseudocode): data_item x := 1 data_item y := 0 swap (x, y); After swap() is performed, x will contain the value 0 and y will contain 1; … Splet22. jul. 2024 · swapping without temp variable is impossible. all you can do is let the compiler worry about creating the temp variable - but it's still there. – Franz Gleichmann Jul 22, 2024 at 5:41 The syntax is simply constructing a tuple with the original values, then deconstructing the tuple into the two target variables.
