const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void (async function () {
    let arg = [];
    let num = 0;
	// 这坑爹的输入输出，这里最关键的是需要退出循环！！！
    while ((line = await readline())) {
		// num就是需要处理的数组的长度，当arg.length为num时退出循环。
		num = num ? arg.push(line) : +line
        if (arg.length === num) break;
    }

    Array.from(new Set(arg))
        .sort((a, b) => a - b)
        .map((e) => console.log(e));
})();
