Q: How do I know which loop to use?

If the English logic implies looking at every item ('for each item'), use a for loop. If it implies waiting for a state change ('keep going until X happens'), use a while loop.

Q: Why should I write logic in English first?

Writing pseudocode or English steps clarifies the algorithmic logic and separates problem-solving from syntax struggles.

Q: How do I handle 'find all' vs 'find first'?

'Find all' requires accumulating results (like pushing to a new array) and letting the loop finish. 'Find first' requires returning or breaking immediately upon finding the match.

Question 1

What if the list is empty?
