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
    let input = ''

       input = line;
    }
    const token  = input.split('');
    const [first,second,...rest] = token;

        a: 10,
        b: 11,
        c: 12,

        e: 14,
        f: 15
    };
    const arr = rest.map(i=> {
        if(/\d/.test(i)){
            return parseInt(i)
        }else {
            return map[i.toLowerCase()]

    }).reverse();
  
    let result = 0
    for(let i = 0;i< arr.length;i++){
        result += Math.pow(16,i) * arr[i]
    }
    console.log(result + '\n')
}()

感觉没有考到算法思想啊。难道是华为对前端在算法方面的思想比较低?
