hard🚀 Application Q15 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand combined blocking logic
The request should be blocked if either the user or the IP exceeds their limit, so the condition must use OR.Step 2: Check condition correctness
if requests_per_user[user] > user_limit or requests_per_ip[ip] > ip_limit: block_request() uses OR with > comparisons, correctly blocking if user or IP exceeds limits.Final Answer:
if requests_per_user[user] > user_limit or requests_per_ip[ip] > ip_limit: block_request() -> Option DQuick Check:
Block if user OR IP exceeds limit [OK]
Quick Trick: Use OR to block if either user or IP exceeds limit [OK]
Common Mistakes:
MISTAKES- Using AND instead of OR
- Using < instead of >
- Checking equality only
