const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
//根据题意, 每个循环对应两行, 一行是数字个数, 一行是哪些数字
//循环第一行次即可
void async function () {
    const firstLine = await readline();
    let t = parseInt(firstLine);
    for (let i = 0; i < t; i++) {
        let res = 0;
        let n = parseInt(await readline());
        let aNum = (await readline()).trim().split(' ').filter(item => item !== '');
        for (let j = 0; j < n; j++) {
            let item = parseInt(aNum[j]);
            res += item;
        }
        console.log(res);
