LeetCode ProblemThreshold Majority Queries
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.

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 <= 104
1 <= nums[i] <= 109
1 <= queries.length <= 5 * 104
queries[i] = [li, ri, thresholdi]
0 <= li <= ri < n
1 <= thresholdi <= ri - li + 1

Frequently Asked Questions
Common questions about solving Threshold Majority Queries and using Phantom Code during coding interviews.
How does Phantom Code help me solve coding problems like Threshold Majority Queries during interviews?
Phantom Code generates complete solutions instantly with proper complexity analysis, letting you focus on explaining your approach and demonstrating problem-solving skills rather than getting stuck on implementation details during high-pressure situations.
What if the interviewer asks follow-up questions or modifications to problems like Threshold Majority Queries?
Phantom Code adapts in real-time. Screenshot the modified problem or use audio mode to capture the interviewer's follow-up, and get an updated solution within seconds — including edge cases and optimizations.
Can Phantom Code help me communicate my solution for problems like Threshold Majority Queries?
Yes. Phantom Code provides step-by-step approach explanations with 3 progressive thoughts, so you can walk through your solution naturally. It also provides time and space complexity analysis to discuss trade-offs.
How does Phantom Code assist with different programming languages for Threshold Majority Queries type problems?
Phantom Code supports 11 programming languages including Python, Java, C++, JavaScript, TypeScript, Go, Rust, Ruby, Swift, Kotlin, and C#. Set your preferred language and get idiomatic solutions.
What coding mistakes does Phantom Code help me avoid during Threshold Majority Queries interviews?
Phantom Code catches common mistakes like off-by-one errors, missing edge cases, incorrect base conditions, and suboptimal approaches. It provides clean, well-structured code that handles all edge cases.
Is Phantom Code detectable when solving problems like Threshold Majority Queries during live interviews?
No. Phantom Code runs as an invisible desktop overlay that doesn't appear in screen shares, recordings, or proctoring software. It works with Zoom, HackerRank, CodeSignal, CoderPad, and all major platforms.
How does Phantom Code help when I'm struggling with Threshold Majority Queries style questions under pressure?
The AI provides structured guidance: first the approach (what algorithm/data structure to use and why), then the implementation with clean code, and finally complexity analysis. This helps you think clearly even under pressure.
Does Phantom Code work for the coding platforms used in Threshold Majority Queries interviews?
Yes. Phantom Code works with all major coding platforms including LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, and any browser-based coding environment.
