How to use this list? 
- These numbers are Leetcode problem numbers
- Do 3 patterns at a time, not all 30 together.
- For each pattern, solve the first 2 to understand the idea, the next 2 to get repetition, and the last 2 to stretch yourself.
- After every pattern, write one reusable template from memory.
- Do not just “solve and move on.” Ask: what signal in the question pointed to this pattern?
- If you get stuck, revisit the same pattern after 3 to 4 days. Pattern recognition is built by spacing, not cramming.

Username reservations are here, as more and more people claim theirs, here’s answers to the top questions you’re asking ⬇️

Q: Are usernames mandatory?

A: Nope, they are optional.

Q: What if the username I want isn’t available?

A: There’s a few reasons you might not be able to reserve the username you want:

1) It’s an existing Instagram or Facebook username; these are reserved for their owners.

2) We’ve held well-known names and some variations of them - like public figures, celebrities, government entities and Meta-verified accounts - so they can only be claimed by their legitimate owners. If you try to reserve those, the system will say it’s not available.

3) Someone already claimed a common name, in that case use the username generator.

Q: What if someone creates a username similar to mine to impersonate me or run a scam, how do you stop someone from pretending to be me?

A: Usernames are not available for messaging yet. When they are, and you get a message from someone new, we’ll let you know the country origin, and a warning for first time outreach. Well-known public-figure names and their variations are held for verified owners. We’re also keeping a close eye on blocks and reports to take action against scammers.

Q: Can random people message me if they know or guess my username?

A: Just like you can’t search for a phone number in WhatsApp, you can’t search for a username. The best way to prevent someone from contacting you is to add a username key and to choose a username that is unique to WhatsApp.

All the current measures remain in place to prevent unwanted contact, including warnings with details about unknown senders (whether they're a new account, if you share groups, what country they're in) and the ability to block and report.

Q: What is a username key?

A: An extra layer of protection you can enable with your username, so that another user will have to know both your username and your username key to contact you. You can reset your key at any time to stop new inbound contact through your username.

Q: Do I have to link my other Meta accounts?

A: If you want the same username as your Instagram or Facebook account, you’ll have to link them. This one of the ways to reduce impersonation and to make sure you’re the legitimate owner of the account. But after that, you can unlink the account if you want, or you can choose a username unique to WhatsApp.

Q: Can I change my username later?

A: Yes, as long as the new one you want is available.

A few more things to keep in mind...

People are making false claims about reserving popular or well-known usernames - this isn't true, only the legitimate account owners are able to reserve well-known public-figure names.

We enabled reservations before usernames launch later this year because we think people will feel strongly about what username they want on WhatsApp. We’re taking our time and listening to feedback so that when it rolls out later this year we get it right.

[avrin @itsavrinwave]

WhatsApp really looked at years of "Can I text you without sharing my number?" and finally said, "Fine." 😂

Usernames are actually a solid privacy upgrade. Less phone number sharing, more control. Better late than never!

[WhatsApp @WhatsApp]

your phone number is personal and sometimes you want to connect without handing it over. that's why we're introducing usernames for WhatsApp.

starting this week, you can reserve a username to use later this year when we launch the feature. It takes just a few seconds, make sure you have the latest version of WhatsApp and then go to Settings > Account > Username.

WhatsApp rolling new updates.....
Have you noticed.

Implement k stacks in an array

Top Telegram user bases:
1️⃣ India – ~104M+ active users
2️⃣ Russia – ~34M
3️⃣ Indonesia – ~27M
4️⃣ USA – ~27M
5️⃣ Brazil – ~22M

When a platform used by 100M+ Indians goes down, even for a few days, people are obviously going to react.

Business logic..🤡.

Why everyone are making such a big deal about a Telegram ban for a few days.
Here's why:
🇮🇳 India is Telegram's biggest market with over 150 million users according to Telegram's founder. That's more people than the population of most countries.

[Taylor Swift @taylorswift13]

It’s a *Toy* Story 🤠
You knew it! My new original song “I Knew It, I Knew You” for Disney and @Pixar’s @toystory 5 will be yours on June 5th. I’ve always dreamed of getting to write for these characters who I’ve adored since I was a 5 year old kid watching the first Toy Story movie. I fell instantly in love with Toy Story 5 when I was lucky enough to see it in its early stages, and I wrote this song as soon as I got home from the screening. Sometimes you just know, right?
You can pre-order now exclusively at https://t.co/NoneI6kxdH and catch Toy Story 5 in theaters June 19th ☁️☁️☁️☁️☁️
