A lice-treatment process — just an idea

Sharing this simply as an idea that some people may find useful. It’s not a recommendation or a medically proven treatment plan, and everyone should be mindful before trying anything on their hair or scalp.

There are different types of anti-lice treatments available. The general process involves applying the treatment thoroughly to the scalp and hair, covering the hair with a cap, and leaving it on for the recommended amount of time. Afterward, the hair is washed very thoroughly.

A conditioner-like product can then be applied, followed by careful combing and inspection to check for any remaining active lice.

For dealing with nits/eggs, the hair can be properly divided into multiple small sections — around 6–8 sections — so that every part of the hair can be handled and checked systematically.

Some salons may also use heat styling/straightening on each section as part of their process. However, please be very mindful before using high heat on the hair or scalp. This is only an idea/method being shared, not something that should be blindly replicated. Excessive heat can damage the hair or cause burns, and straightening should not be assumed to be a medically proven way of eliminating lice or nits.

I’m also not naming the shampoo or mixture because I wasn’t told the exact product or ingredients, and I don’t want to recommend something without knowing what it actually contains.

Again, this is just an idea/process to consider — not a treatment recommendation. Please research properly and be careful before trying anything on your hair or scalp.

Please do proper research and understand the risks before trying anything on your hair or scalp.

For every LeetCode problem, I spend around 30–40 minutes trying to solve it myself.

I keep a rough notebook for all my failed attempts and dry runs(that looks like a mess) , then spend about 5 minutes updating a handbook with:

Pattern recognition

Mistakes I made

One key insight that unlocks the solution

Is this a good way to learn, or am I overdoing it? I'd love to hear how experienced people approach LeetCode

I recently joined a company, but I'm not really interested in the domain I'm working in. If I prepare well over the next few months, is switching to another company/domain as a fresher by next year Jan–June realistic?

Don't have much idea about how early career switches work. Would love to hear your experiences.

Thinking of starting the CSES Problem Set again. I actually began it back in January, but training, internships, and other commitments got in the way, so I had to pause.

Now I'm planning to restart and stay consistent till the end. Before I dive in, do you have any suggestions, tips, or things you wish you knew before starting CSES?

I've been wondering about this. When someone becomes extremely disciplined and focused, it feels like their "frequency" changes. Over time, people who don't match that frequency seem to drift away, while new people with similar goals enter their life.

Is this actually a thing, or is it just psychology and changing priorities? Has anyone experienced this?

I spent a lot of time lurking on this subreddit during my prep, and the advice people shared here genuinely helped me. I recently received an offer, so I wanted to give something back to the community.

This isn't the roadmap—it's simply the one that worked for me. Everyone learns differently, so feel free to tweak it according to your own pace.

📚 Topic Order

>Arrays & Strings → STL (Vectors) → HashMaps → Two Pointers → Prefix Sum → Fast & Slow Pointer (Linked List) → Binary Search →Intervals → Recursion → Backtracking → Stacks → Queues → Sliding Window → Trees → Heaps → Tries → Bit Manipulation → Graphs → Dynamic Programming → Greedy

📺 Resources I Recommend

Arrays & Strings

Use whatever resource matches your learning style. There isn't a single "best" playlist—the important part is understanding the concepts.

STL (Vectors)

Just search "Vectors in STL C++" on YouTube. Any beginner-friendly tutorial will do.

HashMaps

• Shraddha Khapra
• Striver
• Love Babbar
• Luv (especially for unordered_map and C++ STL)

Honestly, this is a one-day topic if you keep practicing the syntax.

Two Pointers

No need to binge an entire playlist.

For problems:

• Striver
• CodeStory with Mik

Focus on recognizing patterns instead of memorizing solutions.

Prefix Sum

Same approach as Two Pointers.

Understand the pattern, solve a handful of quality problems, and move on.

Binary Search

Aditya Verma's playlist is hands down my favorite. Watch it in order.

Also, don't skip Binary Search on Answer (BOSSA)—it's asked surprisingly often in interviews. Striver explains this really well too.

Intervals

This topic can be done afterwards also .

Before starting interval problems, it's enough to know arrays, vector<vector<int>>, sorting, custom comparators, and basic greedy thinking.

I first solved Merge Intervals, then Insert Interval, since both follow the same sort → compare → merge pattern. Meeting Rooms I is simply about detecting overlaps, while Non-overlapping Intervals is the first true greedy problem where you keep the interval with the smaller end time. Meeting Rooms II extends the pattern further by introducing heaps (priority queues).

Recursion & Backtracking

This combination worked perfectly for me:

• Aditya Verma → Concepts
• Shraddha Khapra → Implementation
• Striver → Problem solving

Genuinely one of the best combinations I found.

Linked List / Fast & Slow Pointer

• Shraddha Khapra (Concepts)
• Striver (Questions)
• CodeStory with Mik (Interview-style problems)

Stacks & Queues

Stacks

• Shraddha Khapra
• Aditya Verma

Queues

• Shraddha Khapra

Get comfortable with these before starting Sliding Window or Graphs.

Sliding Window

Don't rush into this topic.

Prerequisites:

• Two Pointers
• Prefix Sum
• Queues

Resources:

• Aditya Verma (Concepts)
• Striver (Practice)

Trees

• Striver (Best structured playlist, in my opinion)
• Shraddha Khapra (Excellent 2-hour revision)

This is one topic where practice matters far more than watching videos.

Heaps (Priority Queue)

Aditya Verma's playlist is excellent and can easily be completed in a couple of days.

Tries

• Shraddha Khapra
• Love Babbar
• Striver

Graphs

I divided Graphs into smaller modules and dedicated 1–2 focused days to each.

I kept separate notes and solved problems every single day.

Overall, this phase took me around a month.

Dynamic Programming

Break it down into:

• Recursion
• Memoization
• Tabulation

Don't jump into DP unless you're already comfortable with recursion.

Bit Manipulation

Striver's playlist is more than enough.

Greedy

I'm currently working through this topic.

📝 A Few Things I Learned

• Don't keep switching between playlists.
• Pattern recognition is far more valuable than watching 100 videos.
• Make your own notes—they're incredibly useful during revision.
• Revise regularly.
• Solve problems consistently.

There will be days when you solve nothing. That's completely normal.

What matters isn't maintaining a perfect streak—it's getting back on track as soon as you can.

If you're feeling overwhelmed or don't know where to begin, I hope this roadmap gives you a little clarity.

If it helps even one person, taking the time to write this post was absolutely worth it.

Happy coding, and all the best! 🙂‍↕️🩷

I'm preparing for SDE interviews and want some honest advice on System Design. Is it mostly theory, or do you need hands-on projects? Is solving common design questions enough, or should you actually implement concepts like caching and queues? What do beginners usually get wrong, and if you were starting today, what roadmap would you follow?

Do they have any projects in the CCM domain at CG Hyderabad? Also, how are the career opportunities and long-term growth prospects in this domain?

I'm about to enter Saturn Antardasha in my Rahu Mahadasha. My Jupiter Antardasha was amazing overall despite the ups and downs. Any idea what themes Saturn Antardasha usually brings or what I can expect?

Hi everyone! First time posting here.

I'm a 2026 graduate currently working at a service-based company and preparing for SDE-1 roles at FAANG/product-based companies.

My preparation is focused on the Striver A2Z Sheet, NeetCode, and consistent LeetCode practice. If I master these resources, will that be enough to clear the DSA/OA rounds for SDE-1, or is a deeper level of preparation expected?

I'd appreciate any advice from people who've gone through the interview process. Thanks!
