Sensor Packet Optimizer 37 — Problem Statement & Solution Guide
Problem Description
Given a sequence of data elements representing sensor and packet metrics, construct an optimal algorithm to evaluate and compute the sum of all numbers greater than K under given operational constraints.
Examples
Input
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10] and K = 5
Output
sum of all numbers greater than 5
Explanation: Step-by-step: We iterate over the input array and sum up all numbers greater than 5. For the given input, the sum is 6 + 7 + 8 + 9 + 10 = 40.
Input
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1] and K = 7
Output
sum of all numbers greater than 7
Explanation: Step-by-step: We iterate over the input array and sum up all numbers greater than 7. For the given input, the sum is 8 + 9 + 10 = 27.
Constraints
- 1 <= N <= 10^5
- -10^4 <= metrics[i] <= 10^4
- 1 <= K <= N
Optimal Approach & Strategy
Use BFS / Union Find technique to process inputs in O(N) linear time.
Brute Force Approach
Check all possible combinations in O(N^2) time.
