 ## 2025-05-20 - Pre-compiling Regex in Loops
 **Learning:** `re.findall(pattern, string)` recompiles (or retrieves from cache) the pattern on every call. In high-frequency functions called inside loops (like complexity estimation), this overhead adds up.
 **Action:** Always pre-compile regexes (`re.compile`) into module-level or class-level constants if they are used repeatedly, especially in tight loops or recursive functions.

+## 2025-05-22 - O(N*M) to O(N) Match Loops Lookup
+**Learning:** Nested loops checking for `item1.id == item2.id` (such as searching solutions for exercises) become major bottlenecks during bulk processing (O(N*M) complexity).
+**Action:** Always refactor these O(N*M) search loops into O(N) hash map lookups by pre-computing a dictionary mapped by the shared key (e.g., `lookup_dict = {item.id: item for item in items}`). When there is a risk of duplicate keys and the original loop used `break` (first match semantics), populate the dictionary manually with `if key not in dict: dict[key] = item`.
