For Day 5, I decided to start following Striver's DSA Sheet — a well-known structured problem set that a lot of people use to build up DSA fundamentals. Today was the first batch of array problems fro

### [#100DaysOfJava — Day 4: Array Practice Problems](https://daultani-gaurav-java.hashnode.dev/100daysofjava-day-4-array-practice-problems?utm_source=hashnode&utm_medium=feed)

After Day 3 introduced arrays, Big O, and my first two search algorithms, Day 4 was a pure practice day — no new theory, just solving classic array problems to actually build muscle memory. Here's eve

Day 3 turned out to be a lot more packed than I expected. What started as "let's learn arrays" quickly turned into arrays + Big O complexity + my first two search algorithms. Here's everything that we

### [Day 2: Conditionals, Loops, and Methods](https://daultani-gaurav-java.hashnode.dev/day-2-conditionals-loops-and-methods?utm_source=hashnode&utm_medium=feed)

Day 1 was all about understanding what happens under the hood when Java code runs. Day 2 shifted gears into actually controlling how that code behaves — decision-making, repetition, and organizing cod

Starting today, I'm committing to writing a daily blog documenting my Java learning journey. Think of this as a public log — partly for accountability, partly to reinforce what I learn by teaching it
