+# Description
+
+2つの整数 $A, B$ の和を求めよ。
+
+なお、この問題は入出力の練習のために用意されている。
+問題の末尾にサンプルプログラムなどが示されているので、参考にせよ。
+
+# Constraints
+
+* $A, B$ は整数
+* $-5000 \leq A, B \leq 5000$
+
+# Input
+1つの入力ファイルは複数のテストケースからなる。
+
+入力ファイルの最初の1行目にはテストケースの個数 $T$ が記される $(1 \leq T \leq 50)$ 。
+
+2行目以降には、$T$ 個のテストケースが記述されており、各テストケースは次の形式で表される。
+
+```
+$A$ $B$
+```
+
+# Output
+各テストケースに対して、$A+B$ を1行ずつ出力せよ。

+コンパイルでは必要に応じて、``-O2``や``-Wall``などのコンパイルオプションを使用するとよいかもしれない。
+
+* ファイルから入力する
+
+```
+./a.out < in.txt
+```
+
+* ファイルへ出力する
+
+```
+./a.out > out.txt
+```
+
+* ファイル入出力を同時に行う
+
+```
+./a.out < in.txt > out.txt
+```
+
+## Java
+
+* コンパイル・実行
+
+```
+javac Main.java
+java Main
+```
+
+* ファイルから入力する
+
+```
+java Main < in.txt
+```
+
+* ファイルへ出力する
+
+```
+java Main > out.txt
+```
+
+* ファイル入出力を同時に行う
+
+```
+java Main < in.txt > out.txt
+```
+
