Question information:Description

Enter two numbers as the number of exchanges, and output the two values after the order of exchange.

Input

Two integers separated by Spaces

Output

Two integers after interchange, separated by Spaces

Sample Input

1 2

Sample output

2 1

Ideas:

My method is to reverse the positions of two numbers in the output. Another method is to assign the value of a to the temporary variable t, and then assign the value of B to a and t to B.

My code (C ++ ):

1 // DTOJ 2704 2 # include <iostream> 3 using namespace std; 4 5 int main () 6 {7 int a, B; 8 cin> a> B; 9 cout <B <"<a; 10 return 0; 11}
