You are given an integer array nums
. A number x
is lonely when it appears only once , and no adjacent numbers (i.e. x + 1
and x - 1)
appear in the array.
Return all lonely numbers in nums
. You may return the answer in any order.
Example 1:
Input: nums = [10,6,5,8]
Output: [10,8]
Explanation:
-
10 is a lonely number since it appears exactly once and 9 and 11 does not appear in nums.
-
8 is a lonely number since it appears exactly once and 7 and 9 does not appear in nums.
-
5 is not a lonely number since 6 appears in nums and vice versa.
Hence, the lonely numbers in nums are [10, 8].
Note that [8, 10] may also be returned.
Example 2:
Input: nums = [1,3,5,3]
Output: [1,5]
Explanation:
-
1 is a lonely number since it appears exactly once and 0 and 2 does not appear in nums.
-
5 is a lonely number since it appears exactly once and 4 and 6 does not appear in nums.
-
3 is not a lonely number since it appears twice.
Hence, the lonely numbers in nums are [1, 5].
Note that [5, 1] may also be returned.
Constraints:
1 <= nums.length <= 105
0 <= nums[i] <= 106
