Class Solution
Medium
You are given a 0-indexed array of positive integers nums
and a positive integer limit
.
In one operation, you can choose any two indices i
and j
and swap nums[i]
and nums[j]
if |nums[i] - nums[j]| <= limit
.
Return the lexicographically smallest array that can be obtained by performing the operation any number of times.
An array a
is lexicographically smaller than an array b
if in the first position where a
and b
differ, array a
has an element that is less than the corresponding element in b
. For example, the array [2,10,3]
is lexicographically smaller than the array [10,2,3]
because they differ at index 0
and 2 < 10
.
Example 1:
Input: nums = [1,5,3,9,8], limit = 2
Output: [1,3,5,8,9]
Explanation: Apply the operation 2 times:
-
Swap nums[1] with nums[2]. The array becomes [1,3,5,9,8]
-
Swap nums[3] with nums[4]. The array becomes [1,3,5,8,9]
We cannot obtain a lexicographically smaller array by applying any more operations.
Note that it may be possible to get the same result by doing different operations.
Example 2:
Input: nums = [1,7,6,18,2,1], limit = 3
Output: [1,6,7,18,1,2]
Explanation: Apply the operation 3 times:
-
Swap nums[1] with nums[2]. The array becomes [1,6,7,18,2,1]
-
Swap nums[0] with nums[4]. The array becomes [2,6,7,18,1,1]
-
Swap nums[0] with nums[5]. The array becomes [1,6,7,18,1,2]
We cannot obtain a lexicographically smaller array by applying any more operations.
Example 3:
Input: nums = [1,7,28,19,10], limit = 3
Output: [1,7,28,19,10]
Explanation: [1,7,28,19,10] is the lexicographically smallest array we can obtain because we cannot apply the operation on any two indices.
Constraints:
1 <= nums.length <= 105
1 <= nums[i] <= 109
1 <= limit <= 109
