Given string, detect all occurrences of the palindrome pattern.
Coding interviews at Morgan Stanley focus on problem-solving approach as much as the final solution. The interviewer wants to see you break down the problem, consider edge cases, and optimize iteratively. Communication throughout the process is key.
What the Interviewer Expects
- Quickly identify the optimal approach and its theoretical basis
- Handle complex algorithm design with multiple interacting components
- Write concise, elegant code under time pressure
- Prove correctness of your approach and discuss alternative solutions
- Optimize beyond the obvious: discuss constant factor improvements
- Address follow-up variations and explain how the solution generalizes
Key Topics to Cover
Graph algorithms and traversal
Data structure selection and trade-offs
Sorting and searching
Time and space complexity analysis
Edge cases and input validation
Dynamic programming and memoization
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 if the input doesn't fit in memory?
- How would you modify your solution to handle streaming input?
- How would you test this solution thoroughly?
- Can you solve this in a single pass?

Problem Analysis
To detect all occurrences of the palindrome pattern in a given string, we first note that a palindrome reads the same forwards and backwards. This suggests that we need to check substrings for symmetr...
Approach
- Iterate through each character in the string. For each character, consider it as a potential center for odd-length palindromes and also check the gap between it and the next character for even-...
