Problem Description

Your task is to
Calculate a + b.

Too easy?! Of course! I specially designed the problem for acm beginners.

You must have found that some problems have the same titles with this one, yes,
all these problems were designed for the same aim.

Input

The input will
consist of a series of pairs of integers a and b, separated by a space, one
pair of integers per line.

Output

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.

Sample Input

1 5

10 20

Sample Output

Problem Description

Your task is to
Calculate a + b.

Input

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.

Output

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.

Problem Description

Your task is to
Calculate a + b.

Input

Input contains
multiple test cases. Each test case contains a pair of integers a and b, one
pair of integers per line. A test case containing 0 0 terminates the input and
this test case is not to be processed.

Output

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.

Problem Description

Your task is to
Calculate the sum of some integers.

Input

Input contains
multiple test cases. Each test case contains a integer N, and then N integers
follow in the same line. A test case starting with 0 terminates the input and
this test case is not to be processed.

Output

For each group of
input integers you should output their sum in one line, and with one line of
output for each line in input.
