Constrained Palindromic Split
Summary
- •Phase 4 / palindromes/dp/partition
- •Reasoning-first competitive programming drill
Problem Description
Given a string S of length N, partition it into the minimum number of contiguous substrings such that each substring is a palindrome and no substring is longer than K. Output the minimum number of cuts needed.
How to read this problem in plain language:
- This is a Phase 4 reasoning drill focused on palindromes/dp/partition.
- Typical lenses to test first: dynamic programming, palindrome, partition.
- Constraints reminder: 1 ≤ ,000; 1 ≤
Mini examples for mental simulation:
1) Boundary example: Describe why this case is tricky. Explain expected behavior and why naive logic may fail.
2) Adversarial example: Adversarial case where naive greedy/local decision looks correct but fails globally.
Lite-mode writing target:
- Write 1~2 observations that shrink the search space.
- Name one final algorithm and state target complexity explicitly.
- Validate with at least 2 edge cases and one hand simulation.
Constraints
- •1 ≤ ,000; 1 ≤
