Tome Signal Synthesizer 37 — Problem Statement & Solution Guide
Problem Description
Given a sequence of data elements representing tome and signal metrics, construct an optimal algorithm to evaluate and compute the target synthesizer value under given operational constraints.
Examples
Input
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 5
Output
40
Explanation: Step-by-step: Given the input array [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] and the target value 5, we first find the index of the first element greater than 5, which is 5. Then we sum up all elements from index 5 to the end of the array, which are 6, 7, 8, 9, 10. The sum is 6 + 7 + 8 + 9 + 10 = 40.
Input
[10, 20, 30, 40, 50], 25
Output
0
Explanation: Step-by-step: Given the input array [10, 20, 30, 40, 50] and the target value 25, we first find the index of the first element greater than 25, which does not exist. Therefore, the sum of elements greater than 25 is 0.
Constraints
- 1 <= N <= 10^5
- -10^4 <= metrics[i] <= 10^4
- 1 <= K <= N
Optimal Approach & Strategy
Use Bitmasking technique to process inputs in O(N) linear time.
Brute Force Approach
Check all possible combinations in O(N^2) time.
