说明

Xiao Ming always tends to ignore the carry when he does decimal addition with paper and pencil.For example,15+17,Xiao Ming will answer 22,because he ignores the carry from the single digits.5+7=12,and the digit 1 is the carry. 

输入格式

The input will consist of a series of pairs of integers a and b(both less than 1000000000),separated by a space, one pair of integers per line.

输出格式

For each pair of input integers a and b you should output the correct answer of the sum of a and b,a space character and Xiao Ming's answer of the sum of a and b in one line,and with one line of output for each line in input.If Xiao Ming's answer begins with zero,don't output unnecessary zero.
