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

void async function () {
    let count = 0
    // Write your code here
    while(line = await readline()){
        let tokens = line.split(' ');
        if (tokens.length > 1) {
            tokens.map(item => {
                count += parseInt(item, 10)
            })
            console.log(count)
        }
    }
}()

简简单单， 需要再循环之前判断一下输入的数据长度大于1 即可
