Make a simple program that reads two variables named A, B. Calculate and print the difference of A and B (A - B).
Input file consist of several test cases. Each test case contains a line and each line will contains two integers A and B (0<A, B<10000 and A>B). Input is terminated by EOF.
For each test case you should output a line. This line contains the value of the difference of A and B.
