【简单】算法nodeJs：记负均正

需要注意如果没有正整数，平均数需要输出0

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

void (async function () {
    // Write your code here
    n = await readline();
    const inputArr = (await readline()).split(" ");
    let sum = 0;
    const p_iArr = [];
    for (let i = 0; i < inputArr.length; i++) {
        if (inputArr[i] < 0) sum++;
        if (inputArr[i] > 0) p_iArr.push(inputArr[i]);
    }
    // console.log(p_iArr)
    let sum_arr = 0;
    for (let i = 0; i < p_iArr.length; i++) {
        sum_arr += parseInt(p_iArr[i]);
    }
    const average = p_iArr.length > 0 ? parseFloat(sum_arr / p_iArr.length) : 0;
    console.log(sum, " ", average);
})();
