Coding Interview Resources (@crackingthecodinginterview) Ingliz til segmentidagi kanali faol ishtirokchi. Hozirda hamjamiyat 52 122 obunachidan iborat bo'lib, Texnologiyalar & Aralashmalar toifasida 2 563-o'rinni va Hindiston mintaqasida 7 263-o'rinni egallagan.

๐Ÿ“Š Auditoriya koโ€˜rsatkichlari va dinamika

ะฝะตะฒั–ะดะพะผะพ sanasidan buyon loyiha tez oโ€˜sib, 52 122 obunachiga ega boโ€˜ldi.

05 Iyun, 2026 dagi oxirgi maโ€™lumotlarga koโ€˜ra kanal barqaror faollikka ega. Oxirgi 30 kunda obunachilar soni 194 ga, soโ€˜nggi 24 soatda esa 11 ga oโ€˜zgardi va umumiy qamrov yuqori darajada qolmoqda.

  • Tasdiqlash holati: Tasdiqlanmagan
  • Jalb etish (ER): Auditoriya oโ€˜rtacha 1.93% darajada jalb etiladi. Nashrdan keyingi dastlabki 24 soatda kontent odatda umumiy obunachilar sonining 0.84% ini tashkil etuvchi reaksiyalarni toโ€˜playdi.
  • Post qamrovi: Har bir post oโ€˜rtacha 1 005 marta koโ€˜riladi; birinchi sutkada odatda 437 ta koโ€˜rish yigโ€˜iladi.
  • Reaksiyalar va oโ€˜zaro taโ€™sir: Auditoriya faol: har bir postga oโ€˜rtacha 2 ta reaksiya keladi.
  • Tematik yoโ€˜nalishlar: Kontent array, stack, algorithm, programming, sort kabi asosiy mavzularga jamlangan.

Type of problem, while solving DSA problem in Array โ— There are many types of problems that can be solved using arrays and different techniques in Data Structures and Algorithms.

You can use a sliding window technique to efficiently search through the array by maintaining a current window of fixed size and updating it as you move forward. ๐Ÿ. ๐“๐ฐ๐จ ๐ฉ๐จ๐ข๐ง๐ญ๐ž๐ซ ๐ฉ๐ซ๐จ๐›๐ฅ๐ž๐ฆ๐ฌ: In these problems, you use two pointers to traverse the array from both ends and find a certain pattern or condition. For example, you can use two pointers to find a pair of elements that sum up to a target value, or to reverse an array. ๐Ÿ‘. ๐’๐จ๐ซ๐ญ๐ข๐ง๐  ๐ฉ๐ซ๐จ๐›๐ฅ๐ž๐ฆ๐ฌ: In these problems, you are asked to sort an array in a certain way, such as in ascending or descending order, or according to certain criteria such as frequency or value.

Commonly asked System Design CONCEPT BASED interview topics - 1. Horizontal vs Vertical Partitioning: Vertical partitioning splits tables by columns, often separating different features. Horizontal partitioning splits tables by rows, distributing data across multiple servers. Vertical organizes data logically, while horizontal improves scalability + performance. 2. Apache Kafka: Kafka is a distributed streaming platform using a publish-subscribe model. It's fast due to the sequential disk I/O, zero-copy principle, and efficient batching of messages. 3. Rate Limiter: A rate limiter controls the rate of requests a client can make to a service. It prevents overload and ensures fair resource usage. 4. JWT vs OAuth vs SAML: JWT is a compact, self-contained token for secure information transmission. OAuth is an authorization framework for delegated access. SAML is an XML-based standard for exchanging authentication and authorization data. 5. Single Sign-On (SSO): SSO allows users to access multiple applications with one set of credentials. It typically uses a central authentication server and protocols like SAML/OAuth. 6. Microservices vs Monolithic Architecture: Microservices architecture breaks an application into small, independent services. Monolithic architecture is a single, tightly-coupled unit. Microservices offer scalability while monoliths are simpler to develop + deploy. 7. Reverse Proxy vs Forward Proxy: A reverse proxy sits in front of web servers, forwarding client requests to backend servers. A forward proxy sits in front of clients, forwarding their requests to the internet. Reverse proxies are used for load balancing and security, while forward proxies are used for anonymity and filtering. 8. CAP Theorem: The CAP theorem states that a distributed system can only provide two of three guarantees: Consistency, Availability, and Partition tolerance. In practice, partition tolerance is necessary, so systems must choose between consistency and availability during network partitions. 10. Efficient Caching Strategy: Implement multi-level caching (browser, CDN, application server, database). Use appropriate cache invalidation strategies (TTL, event-based). Consider cache coherence for distributed systems. Best DSA RESOURCES: https://topmate.io/coding/886874 All the best ๐Ÿ‘๐Ÿ‘
