Threshold Majority Queries
You are given an integer array nums of length n and an array queries, where queries[i] = [li, ri, thresholdi].
You are given an integer array nums of length n and an array queries, where queries[i] = [li, ri, thresholdi].
Return an array of integers ans where ans[i] is equal to the element in the subarray nums[li...ri] that appears at least thresholdi times, selecting the element with the highest frequency (choosing the smallest in case of a tie), or -1 if no such element exists.
Example 1
Input: nums = [1,1,2,2,1,1], queries = [[0,5,4],[0,3,3],[2,3,2]]
Output: [1,-1,2]
Example 2
Input: nums = [3,2,3,2,3,2,3], queries = [[0,6,4],[1,5,2],[2,4,1],[3,3,1]]
Output: [3,2,3,2]
Constraints
- 1 <= nums.length == n <= 10^4
- 1 <= nums[i] <= 10^9
- 1 <= queries.length <= 5 * 10^4
- queries[i] = [li, ri, thresholdi]
- 0 <= li <= ri < n
- 1 <= thresholdi <= ri - li + 1
