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()){
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);
}
})();
