DWITE Online Computer Programming Contest, November 2009, Problem 2

The basic idea behind DWITE's judge is to run your programs against the test input, and compare the result against the test output. To get a better understanding, here we'll make a miniature judge that tests a simple addition function.

The input will contain ~5~ sets of data: each ~5~ lines of two non-negative integers, ~n_1~ and ~n_2~ ~(0 \le n_1, n_2 \le 100)~ separated by a space. ~5~ lines of "expected" output follow. That is, the input is a total of ~50~ lines.

You "run a solution" by adding the input integers, and then checking if it matches the number in the "expected output" part. Add 1 point for each match, 0 for different numbers.

The output will contain 5 lines, each a score for a set.

Explanation of the sample input below:

• ~1 + 2 = 3~; score point
• ~2 + 3 = 5~; score point
• ~3 + 4 = 7~; score point
• ~4 + 5 \ne 10~; no point
• ~5 + 6 = 11~; score point
