mediumArraysPattern: Kadane's / Prefix Sum
Optimal Single Transaction Gain Solution
Problem Statement
Given a sequence of integers representing daily market values and a specified interval defined by `start_index` and `end_index` where 0 ≤ `start_index` < `end_index` < sequence length, determine the maximum achievable gain from a single acquisition and disposal within the designated interval.
Examples
Example 1:
Input:{"marketValues":[7,1,5,3,6,4],"start_index":0,"end_index":5}
Output:5
Example 2:
Input:{"marketValues":[7,6,4,3,1],"start_index":0,"end_index":4}
Output:0
Constraints
- 1 <= length of array <= 10^5
- 0 <= stock prices <= 10^4
Time: O(n) Space: O(1)
The optimized approach utilizes Kadane's algorithm and prefix sum technique to find the maximum subarray sum within the given range, resulting in a time complexity of O(n).
