    [DSA] Sliding Window Algorithm

    The Sliding Window Algorithm is a powerful technique used to reduce the time complexity of problems involving arrays or strings—specifically those that require finding a sub-segment that meets certain criteria.Instead of using nested loops O(n^2), the sliding window maintains a dynamic range that "slides" across the data, usually bringing the complexity down to O(n). Problem:Find the maximum sum of a contiguous subarray of size `k`. public class SlidingWindow { public static int findMaxSum(int[] arr, int k) { int n = arr.length; if (n k) return -1; int windowSum = 0; // 1. Compute sum of the first window for (int i = 0; i k; i++) { windowSum += arr[i]; }int maxSum = windowSum; // 2. Slide the window from index k to n-1 for (int i = k; i n; i++) { // Add the next element, remove the first element of the previous window windowSum += arr[i] - arr[i - k]; maxSum = Math.max(maxSum, windowSum); } return maxSum; } }

    [System Design] The Foundation & The Framework EP01

    Episode 1 of your 3-part System Design Interview deep-dive podcast series! This episode focuses on how interviewers at FAANG and Tier-1 financial institutions evaluate you—which is how you think, not just what you know. The hosts will cover: The RADIO Framework: The 5-step, 45-minute blueprint for every interview: Requirements, API Design, Data Model, Infrastructure, and Optimise & Operate.The #1 Trap for Candidates: Why skipping Non-Functional Requirement (NFR) clarification—like asking about SLAs, active users, and data volume before jumping in—is the main reason senior candidates fail.Scalability & The CAP Theorem: A deep dive into Horizontal vs. Vertical scaling, when to use Sharding, and the core trade-offs of the CAP Theorem (Consistency vs. Availability) when network partitions are inevitable.Episode 2 The Database Decision Matrix: How to clearly articulate when to use an RDBMS (PostgreSQL) for ACID compliance versus a Document Store (MongoDB) or a Wide-Column Store (Cassandra) for massive write scale.Caching Architectures: Explaining the trade-offs between Cache-Aside, Write-Through, and Write-Behind patterns, as well as how to avoid system crashes like Cache Stampedes and Avalanches.Kafka Deep Dive: Unpacking how to confidently discuss Kafka offsets, consumer groups, and the critical difference between "At-least-once" delivery and "Exactly-once" financial settlement semantics.Episode 3 The Estimation Toolkit: The latency numbers you absolutely must memorize (like L1 cache taking ~1 ns, and a cross-region WAN round-trip taking ~150 ms) and the formulae for calculating daily storage and peak QPS.Designing a Fintech Payment System: A walkthrough of designing for extreme correctness (99.999% availability), including the Saga Pattern for distributed transactions, Idempotency Keys to prevent double-charging, and the Outbox Pattern.The Minute-by-Minute Playbook: How to perfectly pace your 45-minute interview and the exact trade-off language senior engineers use to close strong.
