36岁又失业了，之前经常加班，现在好了，又焦虑的；简历投到 “手软” 毫无回音，阿里外包面试栽在这道数组组合题，同行们也这样吗？下面给出deepseek的答案，共勉

算法题目：题目整数数组，组合后返回最大的组合数，列：[2,5,30,34,9] 返回 9534302；

public class demo {

    public static void main(String args[]) {

        int[] arr = { 2,5,30,34,9};
        System.out.println(getMax(arr));
    }

    public static String getMax(int[] nums) {
        if (nums == null) {
            return "";
        }
        String[] numsStr = new String[nums.length];
        int i = 0;
        for (int num : nums) {
            numsStr[i++] = num + "";
        }
        Arrays.sort(numsStr, new Comparator<String>() {
            public int compare(String str1, String str2) {
                String temp1 = str1 + str2;
                String temp2 = str2 + str1;
                return (-temp1.compareTo(temp2));
            }
        });
        StringBuilder sb = new StringBuilder();
        for (String s : numsStr)
            sb.append(s);
        return sb.toString();
    }
