Sort and Rearrange: Efficient Algorithms for Diverse Challenges
Sort and Rearrange: Efficient Algorithms for Diverse Challenges
This problem presents three distinct algorithmic challenges:
- Longest Increasing Subsequence (LIS): Write an efficient algorithm to return the length of the longest increasing subsequence in an integer array.
- Classroom Rearrangement: Design a function that rearranges a classroom so no adjacent students share the same team.
- File Sorting: How would you sort 50 numbers in a file, and how would your approach change for one million numbers?
