X'inhu strateġija tajba għall-approċċ ta' problemi tal-intervista tal-kodifikazzjoni?

Strateġija affidabbli hija **ifthem, ippjana, imbagħad kodiċi** — qatt ma taqfzx direttament għat-tipwriting. Approċċ strutturato jiskopri każijiet ta' borża kmieni u jikommunika ċ-ċ-ħsieb tiegħek b'ċar.

## Framework pass-by-pass

```text
1. CLARIFY  -> restate the problem, ask about inputs, ranges, edge cases
2. EXAMPLES -> work a small example by hand; note edge cases (empty, 1, dups)
3. BRUTE FORCE -> state the obvious solution and its complexity
4. OPTIMIZE -> spot the bottleneck; pick a pattern (hash, two-pointer, DP...)
5. CODE     -> write clean, modular code while talking through it
6. TEST     -> trace examples, check edges, fix bugs
7. ANALYZE  -> state final time and space complexity
```

## Rikonoxxenza tal-mudell

| Sinjal | Teknika probabbli |
|--------|------------------|
| array mressaq / par | two pointers / binary search |
| "subarray / substring" | sliding window / prefix sum |
| "count / seen before" | hash map |
| "all combinations" | backtracking |
| overlapping subproblems | dynamic programming |
| graph / grid reachability | BFS / DFS |

## Eżempju ta' mentalità

```python
# Always START from the brute force, THEN optimize.
# Brute force two-sum is O(n^2); a hash map makes it O(n).
# State this trade-off out loud before coding.
```

## Pitfalls

Alla kodifika f'silenzju, alla ignora każijiet tal-borders, u alla ħaggef prematuru. Ikseb xi ħaġa korretta l-ewwel, imbagħad itjebba'.

## Għaliex dan huwa importanti

Proċess ripettibbli iżommok kalm u jipprevjeni l-kodifikazzjoni tal-panika li tipproduċi soluzzjonijiet żbaljati.

Ip-parla ta' kull pass jippermetti lill-intervistatur li jsegwi r-raġunament tiegħek u jagħtik suġġerimenti — huma jevalwaw *kif* inti taħseb, mhux biss ir-risposta finali.

L-istess dixxiplina tifhem-ippjana-ttestja jagħmilok inġinier aħjar fuq problemi reali u ambigwi.
