Step-by-Step Solution
Solution:
Step 1: Calculate tokens refilled after 3 seconds
Since refill rate is 1 token per second, after 3 seconds, 3 tokens are added.Step 2: Check max tokens limit
The bucket max is 5 tokens, so 3 tokens fit without exceeding the max.Final Answer:
3 tokens -> Option AQuick Check:
3 seconds * 1 token/sec = 3 tokens [OK]
Quick Trick: Multiply seconds by refill rate, cap at max tokens [OK]
Common Mistakes:
MISTAKES- Assuming bucket fills instantly to max
