没啥好说的，刷的第一题，测试环境用

var readline = require('readline');
var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});
rl.on('line', function (cmd) {
  var bai = Math.floor(cmd/100);
  var shi = Math.floor(cmd%100/10);
  var ge = Math.floor(cmd%10);
  var str = '';
  for(var i = 0;i < bai; i++) {
    str += 'B';
  };
  for (var i = 0; i < shi; i++) {
    str += 'S';
  };
  for (var i = 0; i < ge; i++) {
    str += (i + 1);
  };
  console.log(str);
});

乙级 1038 最后一个测试点错误，请问你有办法吗？

var i = 1;
var grade;
require("readline")
    .createInterface(process.stdin, process.stdout)
    .on("line", function (str) {
    if (i == 1) {
        i++;
        return;
    }
    if (i == 2) {
        grade = str.split(" ").map(function (item) { return parseInt(item); });
        i++;
        return;
    }
    if (i == 3) {
        var match_1 = str.split(" ").map(function (item) { return parseInt(item); }).slice(1);
        var result_1 = match_1.map(function () { return 0; });
        grade.forEach(function (item) {
            var index = match_1.indexOf(item);
            if (index != -1)
                result_1[index]++;
        });
        console.log(result_1.join(" "));
        process.exit(0);
    }
});
