Optimize partitioning for streaming input
Last updated: June 14, 2026
Quick Overview
Given a continuous stream of input data, design an algorithm to optimize the partitioning of this data into fixed-size chunks while minimizing latency and maximizing throughput. Your solution should handle dynamic input sizes and should return the partitions as an array of arrays, ensuring that each partition does not exceed the specified size limit.

Given a continuous stream of input data, design an algorithm to optimize the partitioning of this data into fixed-size chunks while minimizing latency and maximizing throughput. Your solution should handle dynamic input sizes and should return the partitions as an array of arrays, ensuring that each partition does not exceed the specified size limit.
Brex uses this problem in the Take-home Project to evaluate your algorithmic thinking. They expect you to discuss multiple approaches, analyze trade-offs between them, and implement the optimal solution with clean, readable code.
What the Interviewer Expects
- Recognize the underlying problem pattern (sliding window, two pointers, BFS/DFS, etc.)
- Discuss multiple approaches and trade-offs before coding
- Implement an optimal solution with clean, production-quality code
- Handle all edge cases including boundary conditions and invalid input
- Optimize both time and space complexity with clear justification
- Test your solution systematically with well-chosen examples
Key Topics to Cover
How to Approach This
- Clarify input constraints and edge cases before writing code.
- Walk through your approach verbally and confirm with the interviewer before coding.
- Start with a brute force solution, then optimize. Mention time and space complexity.
- Test your solution with examples, including edge cases like empty input or duplicates.
- Consider common patterns: sliding window, two pointers, hash map, BFS/DFS, dynamic programming.
Possible Follow-up Questions
- What happens if the input contains duplicates?
- How would you modify your solution to handle streaming input?
- What is the worst-case input for your solution?

Problem Analysis
The problem requires us to partition a continuous stream of input data into fixed-size chunks while minimizing latency and maximizing throughput. The key pattern here is the sliding window techniq...
Approach
- Initialize Variables: Start with an empty list to hold the partitions and a temporary list to accumulate the current chunk.
- Iterate Through Stream: As new data elements are streamed in, ...
