#DailyLearning-November [Day 4/20]#20DaysOfLearningChallenge 🗓 **Today's Focus:** Sliding Window Problems & MongoDB Aggregations 💡 **What I Learned Today:** 1. **Sliding Window Technique**: I solved five problems using the sliding window technique, focusing on optimizing subarray operations and string manipulation: - [Longest K Unique Characters Substring](https://lnkd.in/gj8yUacW) - [Minimum Window Substring](https://lnkd.in/g-EYU544) - [Fruit Into Baskets](https://lnkd.in/g7xBPuuq) - [Longest Substring Without Repeating Characters](https://lnkd.in/gYpbRtP4) - [Substrings of Size Three With Distinct Characters](https://lnkd.in/gxsVs6RK) 2. **MongoDB Aggregations**: Explored aggregation concepts using **Masai Prepleaf** resources. - **Aggregation - 1**: Basics of grouping, filtering, and projecting data. - **Aggregation - 2**: Advanced operations like `$group`, `$lookup`, and `$unwind`, enhancing my ability to query and analyze complex datasets efficiently. 🚀 **How I Applied It:** - Practiced solving problems requiring efficient window management and string operations to improve my algorithmic thinking. - Worked on MongoDB aggregation pipelines, applying what I learned to analyse structured and unstructured data. 📈 **Next Steps:** Tomorrow, I’ll dive deeper into MongoDB queries and explore advanced Express concepts like middleware chaining. 🔗 **Resources Used:** - [Masai Prepleaf](https://www.prepleaf.com) - GeeksforGeeks - LeetCode 🔗 You can check my work at : https://lnkd.in/dTx6v-6a https://lnkd.in/gBi4h7CE #Masai #Prepleaf #DailyLearning #SlidingWindow #MongoDB #ProblemSolving #CodingSkills #WebDevelopment Masai Prepleaf by Masai
