2089. 找出数组排序后的目标下标](https://leetcode.cn/problems/find-target-indices-after-sorting-array/description/)

利用sort排序，遍历找出与目标值target一样的数字的下标。

class Solution {
public:
    vector<int> targetIndices(vector<int>& nums, int target) {
        vector<int> res;
        sort(nums.begin(),nums.end());
        for(int i=0;i<nums.size();i++){
            if(nums[i]==target){
                res.push_back(i);
            }
        }
        return res;
    }
};
