Given a sequence of integer numbers, print the first pair $x$ and $y$ with exactly an integer in the middle, and such that the remainder of divide $x+y$ by 100 is 1.

Input

Input is a sequence of, at least, three integer numbers. In absolute value, none of them is greater than 1000000.

Output

Your program must print the first pair of integer numbers $x$ and $y$ with exactly an integer in the middle in the input sequence, and such taht the remainder of divide $x+y$ by 100 is 1. If this pair does not exist, indicate it. Follow the format of the examples.

Observation

Be careful with the modulo of negative numbers!
