Rest API - Rate Limiting and Throttling

You have a list of API response times in milliseconds: times = [120, 100, 130, 90, 110, 150]. Using a sliding window of size 3, how would you find the maximum average response time for any window?

ACalculate the average of each window and track the maximum average

BSum all response times and divide by total number of elements

CFind the maximum single response time in the list

DSort the list and pick the last three elements

Step-by-Step Solution

Solution:

Step 1: Understand the problem requirement
We need the maximum average of any consecutive 3 response times (sliding window size 3).
Step 2: Calculate average for each window and track max
Calculate sum of each window of size 3, divide by 3, and keep the highest average.
Final Answer:
Calculate the average of each window and track the maximum average -> Option A
Quick Check:
Max average = max of window averages [OK]

Quick Trick: Average each window, track max average [OK]

Common Mistakes:

MISTAKES

Calculating average of entire list instead of windows
Picking max single value instead of average
