Interview Problem: Peeking Iterator

Your solution is excellent and matches the reference solution in both approach and efficiency. Here are some observations:

Strengths:

• Correct implementation of all three methods (peek, next, hasNext)
• Proper use of caching to achieve O(1) operations
• Clean, readable code with good use of Java conventions
• Proper use of @Override annotation
• Concise use of ternary operator

Minor suggestions for improvement:

1. Variable naming: Consider using more descriptive names like nextElement or cachedNext instead of elem for better readability.
2. Constructor robustness: Your constructor checks iterator.hasNext() before calling next(), which is good defensive programming. However, since the problem guarantees at least one element, you could simplify this. But keeping the check makes your code more robust to edge cases.
3. Code comments: Adding brief comments explaining the caching strategy could help future readers understand the design choice.

Overall, this is a well-implemented solution that correctly solves the problem with optimal time and space complexity.

VERDICT: PASS
