JS如何获取一个数字数组并返回最大的可传递组合数

function getMaxCombination(numbers) {
  numbers.sort((a, b) => b - a); // 按照从大到小的顺序排序数组

  let maxCombination = 0;

  for (let i = 0; i < numbers.length; i++) {
    for (let j = i + 1; j < numbers.length; j++) {
      const combinedNumber = Number(numbers[i].toString() + numbers[j].toString());
      if (combinedNumber > maxCombination) {
        maxCombination = combinedNumber;
      }
    }
  }

  return maxCombination;
}

const numbers = [1, 2, 3, 4, 5];
const maxCombination = getMaxCombination(numbers);
console.log(maxCombination); // 输出：54321
