The Longest Subarray of 1’s After Deleting One Element problem is a frequently asked interview question that tests your understanding of sliding window techniques and careful handling of constraints. The task is simple but tricky: given a binary array, delete exactly one element and return the length of the longest subarray consisting only of 1s. … Read more
The Max Consecutive Ones III problem from LeetCode 75 is a classic interview question that tests your mastery of the sliding window technique. This problem focuses on array traversal, window adjustment and constraint handling. The challenge: given a binary array nums and an integer k, find the maximum number of consecutive 1s in the array … Read more
Artificial Intelligence (AI) is no longer just an abstract concept studied in research labs- it’s shaping industries, driving innovation and transforming the way humans interact with technology. To build truly intelligent systems, however, learners need both a solid theoretical foundation and practical hands-on tools. That’s where Artificial Intelligence: Foundations of Computational Agents (3rd Edition) by … Read more
Artificial Intelligence is entering a new era. No longer limited to answering questions or generating text, today’s systems are evolving into autonomous agents – intelligent entities that can reason, plan, collaborate, and act. This shift requires a structured way of thinking about design and implementation. Antonio Gulli’s Agentic Design Patterns: A Hands-On Guide to Building … Read more
In recent years, the rise of large language models (LLMs) has opened the door for more intelligent and capable agents. However, training agents to perform multi-step tasks reliably remains challenging, primarily due to the need for careful reward function engineering. Enter (ART – Agent Reinforcement Trainer) an open-source framework designed to streamline reinforcement learning (RL) … Read more
If you are working with big data, distributed computing, or data pipelines, then Apache Spark is likely already on your radar. And when it comes to using Spark with Python, PySpark is the go-to library. However, with so many functions and modules (SQL, DataFrames, MLlib, Streaming), remembering everything can be overwhelming. That’s why this Cheatsheet … Read more
The Maximum Average Subarray I problem from LeetCode 75 is a common interview question that tests your understanding of sliding window techniques, array traversal, and optimization. The task is straightforward: given an integer array and a window size k, find the contiguous subarray of length k that has the maximum average. In this blog post, … Read more
