Write a program to swap the values of two variables. The program will ask the user to input variables x and y with numerical values. You must write code that exchanges their values: the value of x after your code runs must equal the value that y had before your code ran, and the value of y after your code runs must equal the value that x had before your code ran.

寫一個交換兩個變數的程式

Example input:

3
5

Example output:

5
3

Remember: Your output may be 100% correct, but your code matters!
