Subarray Fuel Capacity Matches Solution
Problem Statement
Given an array of integers `distances` representing space station intervals and a target integer `fuelCapacity`, find all distinct subarrays with sums equal to `fuelCapacity`, excluding empty subarrays but including subarrays of length 1.
Constraints
- 1 <= array length <= 1000
- 1 <= distance values <= 10000
- 1 <= target fuel capacity <= 100000
Time: O(n²) Space: O(n)
The optimal approach uses a two-pointer technique to efficiently generate all possible subarrays and calculate their sums. This approach has a time complexity of O(n²) but is more efficient than the brute-force approach due to the reduced number of iterations.
