很漂亮的代码 object转array及object排序的运用 完整代码如下：
const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
let lines = [];
void async function () {
// Write your code here
while(line = await readline()){
lines.push(line);
if (lines.length - 1 == parseInt(lines[0])) {
for (let i = 1; i <= lines.length; i++) {
console.log(maxBeauty(lines[i]));
}
}
}
}()
function maxBeauty(str){
let arr = str.split('');
let object = arr.reduce((a, b) => ({...a, [b]: 1 + (a[b] = a[b] ? a[b] : 0)}), {});
let m = 26
let ordered = Object.entries(object).sort(([,a],[,b]) => b-a).reduce((r, [k, v]) => ({ ...r, [k]: m-- }), {});
let res = 0
for (let i = 0; i < str.length; i++){
res += ordered[str[i]]
}
return res;
}
