Скачать или смотреть Longest Common Prefix | Java | Detailed Video | Leetcode Problem

Alright, let’s be real—if you’re prepping for coding interviews and haven’t bumped into the Longest Common Prefix problem yet, are you even trying?

Yeah, this one pops up everywhere. In this video, I’m tearing into it, peeling back the layers so it actually makes sense instead of sounding like algorithmic word salad.

So, here’s the deal:
▶️ Horizontal Scanning ApproachThis one’s like the chill, no-nonsense cousin of the group. You just line up your strings, chop off what doesn’t match, and keep going till you’ve got something that fits everyone. It’s super straightforward—basically the “let’s not overthink it” way. Honestly, if you’re under interview pressure, this is your go-to.

▶️ Divide and Conquer ApproachAlright, now we’re flexing a bit. You split the list, solve for each chunk, then mash the results together. Not only does it speed things up, but it also makes you look like you actually know what you’re doing. Interviewers eat this stuff up.

So, what’s in this video for you?
Zero-fluff explanations of both methods—no jargon tornadoes.
I’ll walk you through the code, step by step, in Java. If you hate getting lost in code, don’t worry.
We’ll dry run with classics like [“flower”, “flow”, “flight”]—because, of course we will.
Sneaky interview tricks and how to take your solution from “meh” to “heck yeah.”

Honestly, if you wanna roll into your next interview and drop knowledge bombs, you need these techniques in your back pocket. Pop some popcorn, grab your coffee, and let’s turn this string problem into child’s play.

💬 Thinking about the DP (Dynamic Programming, not Dr Pepper) version? Drop a “PREFIX” in the comments and I might just whip it up.

🧵 Tag a buddy who needs the practice or just save this for that inevitable “oh no, I forgot everything” moment before your next interview. 👨‍💻👩‍💻
