Dear Participants,

Welcome to Week 2 of the challenge! After mastering number-based logic in Week 1, it’s time to shift your focus to string manipulation and pattern recognition. This week’s problems are designed to sharpen your understanding of how to efficiently work with characters and sequences.

Problem Topics:

• Traversing and analyzing digit sequences

• Working with binary strings and alternating patterns

• Identifying and comparing palindromic substrings

What to Expect:

• Challenges that test your grasp of string-based algorithms

• A focus on identifying patterns, transformations, and edge cases

• The need for precise, optimized implementations that handle a variety of input formats

Why Participate?
String problems are common across interviews, online judges, and competitive contests. This week gives you the opportunity to build confidence in handling character-based data, improve your logical reasoning, and continue climbing the leaderboard.

We’re excited to see your approaches and creativity in tackling these problems.

Best Regards,
Team A*
