class Solution:
    def targetIndices(self, nums: List[int], target: int) -> List[int]:
        nums.sort() # 按照从小到大排序
        
        left, right = 0, len(nums)-1
        while(left <= right):
            mid = (left+right)//2
            if nums[mid] >= target:
                right = mid-1
            elif nums[mid] < target:
                left = mid+1
        
        res = []
        for i in range(left, len(nums)):
            if nums[i] == target:
                res.append(i)
            else:
                break
        return res
