Greedy Algorithms - Assign Cookies
What is the output of the optimal greedy Assign Cookies code when given the edge case input g = [0] and s = []?
What is the output of the optimal greedy Assign Cookies code when given the edge case input g = [0] and s = []?
medium🧾 Code Trace Q4 of Q15
Step-by-Step Solution
Solution:
Step 1: Check loop conditions
g=[0], s=[], so len(s)=0. Loop condition j < len(s) is false immediately.Step 2: Loop never runs, count remains 0
Function returns count=0 safely without error.Final Answer:
Option B -> Option BQuick Check:
Empty cookie list means no children content [OK]
Quick Trick: Empty arrays skip loops safely [OK]
Common Mistakes:
MISTAKES- Assuming error on empty input
- Off-by-one errors in loop conditions
- Returning None instead of count
Trap Explanation:
PITFALL- Candidates expect runtime error but code handles empty arrays gracefully.
Interviewer Note:
CONTEXT- Tests handling of edge cases and boundary conditions in code trace.
