Your task is to Calculate a + b.
Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line.
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
