2905. Find Indices With Index and Value Difference II
Problem Explanation
Explanation:
To solve this problem, we can iterate through the given array nums and store the index and value in a hashmap. While iterating, we check if there exists another index (j) such that abs(i - j) >= indexDifference and abs(nums[i] - nums[j]) >= valueDifference. If such a pair is found, we return the indices i and j.
Time Complexity:
The time complexity of this approach is O(n), where n is the length of the input array nums.
Space Complexity:
The space complexity of this approach is O(n) to store the indices and values in the hashmap.
:
Solution Code
import java.util.*;
class Solution {
public int[] findIndices(int[] nums, int indexDifference, int valueDifference) {
Map<Integer, Integer> map = new HashMap<>();
for (int i = 0; i < nums.length; i++) {
if (map.containsKey(nums[i])) {
int j = map.get(nums[i]);
if (Math.abs(i - j) >= indexDifference && Math.abs(nums[i] - nums[j]) >= valueDifference) {
return new int[]{i, j};
}
}
map.put(nums[i], i);
}
return new int[]{-1, -1};
}
