const rl = require("readline").createInterface({ input: process.stdin });

void async function () {
    // Write your code here
    while(line = await readline()){
        let tokens = parseInt(line.split(' '));
        tokens = tokens.toString(2).split("");
        let ans = 0;
        for( let i = 0; i < tokens.length; i++){
            ans += parseInt(tokens[i]);
        }
        console.log(ans);
    }
}()

我的方法

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
while(line = await readline()){
console.log(Number(line).toString(2).split('1').length -1)
}
}()

悠哈优哈的方法

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
    while ((line = await readline())) {
        console.log(Number(line).toString(2).replace(/0/g, "").length);
    }
})();
