Given two variables, x and y, swap two variables without using a third variable. Example Given x =10, y =5 Return15. 思路:考察位运算,异或。 同一个数异或两次还是其本身。 1classSolution {2public:3/**4* @param x an integer5* @param y an integer6* @return nothing7*/8voidswap(int&x,int&y) {9//Write your code here10x =...

The logic toswap the two arrays without using a third variableis as follows ? for(i=0;i<size;i++){first[i]=first[i]+sec[i];sec[i]=first[i]-sec[i];first[i]=first[i]-sec[i];} Program The following C program swaps two arrays without using a temporary variable. It reads the ...
The simplest method to swap two variables is to use a third temporary variable : define swap(x, y) temp := x x := y y := temp Sample Solution: JavaScript Code: // Declare and initialize two variables, x and y, with the values 20 and 40, respectively.letx=20;lety=40;// Output...
Suppose you have two variables x and y and you want to swap their values. The usual way to do this is using another temporary variable: temp = x; x = y; y = temp; However, the interchange of two variables can be done without the temp variable: ...

This involves creating a third variable, assigning one of the original variables to it, assigning the value of the second variable to the first variable, and then assigning the value ofthe temporary variable to the second variable. This effectively swaps the values of the two variables without ...
