Special Palindrome Split
Summary
- •Phase 1 / strings, palindrome, prefix_suffix
- •Reasoning-first competitive programming drill
Problem Description
Given a string of length n, split it into two non-empty substrings such that both are palindromes. What is the minimal possible length of the longer substring?
How to read this problem in plain language:
- This is a Phase 1 reasoning drill focused on strings, palindrome, prefi.
- Typical lenses to test first: strings, palindrome, split.
- Constraints reminder: 2 ≤ , s consists of lowercase letters
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
- •2 ≤ , s consists of lowercase letters
