Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

// inputに入力データ全体が入る
function Main(input) {
	input = input.split("\n"); // 1行目がinput[0], 2行目がinput[1], …に入る
	// ここに処理を書く
    ss = input[0].split(" ");
	// console.logは標準出力に1行出力します (自動的に最後に改行が入ります)
	console.log(ss[0][0] + ss[1][0] + ss[2][0]);
}
 
// ※この行以降は編集しない (標準入力から一度に読み込みMainを呼び出します)
Main(require("fs").readFileSync("/dev/stdin", "utf8"));

/*

	var score = 0;
	for (var i = 0; i < result.length; i++) {
		if (result[i] == "A") score += 4;
		else if (result[i] == "B") score += 3;
		else if (result[i] == "C") score += 2;
		else if (result[i] == "D") score += 1;
	}
	// console.logは標準出力に1行出力します (自動的に最後に改行が入ります)
	console.log(score / result.length);
}
 
// ※この行以降は編集しない (標準入力から一度に読み込みMainを呼び出します)
