easyLinked ListsPattern: Recursive Approach
Maximum Link List Frequencies Solution
Problem Statement
Given a linked list of frequency and amplitude pairs, provide a recursive function to update the maximum amplitude for each frequency.
Examples
Example 1:
Input:-5, 3, 1, 9, 2, 7, -9
Output:9, 7, 1, 9, 2, 7, 9
Explanation: The maximum amplitude for each frequency is updated in the linked list.
Example 2:
Input:2, 4, 1, 6, 4, 3
Output:6, 6, 1, 6, 4, 6
Explanation: The maximum amplitude for each frequency is updated in the linked list.
Example 3:
Input:10, 10, 10, 10, 10
Output:10, 10, 10, 10, 10
Explanation: Since all frequencies are the same, the maximum amplitude remains the same.
Constraints
- Input linked list may be empty.
- Amplitude values may be non-negative.
- Frequency values may be negative or non-negative.
- Output linked list should have updated maximum amplitude for each frequency.
- The function should return the updated linked list.
Time: O(N) Space: O(N)
We can use a recursive approach with a hash map to store the frequency to maximum amplitude mapping.
