A fixed-size sliding window maintains a constant size as it moves through the data structure. This is useful for problems like finding the maximum sum of a subarray of size k, or calculating moving averages. Variable Size Window A variable-size sliding window can expand or contract based on certain conditions. This technique is often used when you need to find the optimal subarray that satisfies specific criteria. Common Applications:

Here’s what we already know about Noah Hawley’s upcoming series, Alien: Earth. It’s set two years before the events of Ridley Scott’s 1979 masterpiece, Alien. It follows several rival corporations competing over a crashed spaceship that contains multiple alien creatures, including the xenomorph. And one of those corporations will send a group of hybrids—robotic beings with the consciousness of humans—in to get the job done. Which all sounds awesome but, also, tangential to the stories we know a

Last week I sat down with executives from PlayStation and AMD to talk about their multiyear collaboration and what they're hoping to achieve on the PlayStation 5 and beyond. During this intimate dinner, I spoke with Mark Cerny, lead architect on PS5 and PS5 Pro at Sony Interactive Entertainment, alongside Jack Huynh, SVP, GM, Computing and Graphics Group at AMD. Sony PR said the conversation wouldn't touch any next-gen console topics but, per our discussion, future and next-generation hardware
The Tony Hawk games were some of my favorite titles when I was growing up. The soundtracks helped form my musical tastes, and the games helped propel me and my friends to learn to skateboard. So when Microsoft brings Tony Hawk's Pro Skater 3 + 4 to Xbox Game Pass on July 11, I'm going to grab my (virtual) deck and returning to some familiar gaps and rails in the game. Xbox Game Pass Ultimate, a CNET Editors' Choice award pick, offers hundreds of games you can play on your Xbox Series X, Xbox Se
After more than a day of continuous debate, the US Senate passed its version of the budget megabill Tuesday afternoon—with potentially disastrous implications for the future of renewable energy in the country. Among a barrage of bad news for climate initiatives, including a new tax credit for coal and the sunsetting of electric vehicle tax credits, the bill forces an aggressive cutoff for tax credits for wind and solar. The bill ends credits for projects placed in service—a term meaning, essent
Phones kind of look same-y. Headphones don't look that visually different either, whether it's a Sony or a Bose. UK-based tech company, Nothing, took it upon itself to change things up again, giving us a smartphone with a design the likes of which we haven't seen before, and headphones that are sure to turn heads.

Apple is suing a former employee for allegedly stealing confidential Vision Pro headset research before leaving to join Snap’s product design team. In the complaint filed in Santa Clara County Superior Court on June 24th, Apple accuses Di Liu of downloading thousands of documents containing proprietary information from Apple’s internal systems and saving them to his personal cloud storage account in his final days as a senior design engineer for the Vision Pro. According to the lawsuit, Liu fal
“The Glyph interface is not a gimmick,” Nothing founder and CEO Carl Pei told the press as he revealed the Nothing Phone 3 for the first time, shortly before announcing that its new iteration lets you play Spin the Bottle on the back of the phone. It’s mixed messaging, but in Nothing’s defense, you couldn’t accuse them of making that mistake elsewhere. The Phone 3, we’re told, is Nothing’s “first true flagship phone,” a point the company is keen to hammer home: flagship chip, flagship camera, f
After 13 years of deploying robots into its warehouses, Amazon reached a new milestone. The tech behemoth now has 1 million robots in its warehouses, the company announced Monday. This one millionth robot was recently delivered to an Amazon fulfillment facility in Japan. That figure puts Amazon on track to reach another landmark: Its vast network of warehouses may soon have the same number of robots working as people, according to reporting from the Wall Street Journal. The WSJ also reported t

Kerry Wan/ZDNET Pixel phones have an excellent reputation for smart software, but battery life has been a common complaint with Google's smartphones. Thankfully, that same smart software is now improving battery life and longevity, though many features aren't set up for maximum endurance out of the box. I've found that a handful of features can dramatically improve how long your Pixel lasts, both in a single day and over the long haul. Also: Why I recommend this $280 Android phone over cheap m

AMC Theatres is making it easier for moviegoers to know the actual start time of their film screening and avoid sitting through lengthy ads. A new notice has started appearing when people purchase tickets via the AMC website, warning that “movies start 25-30 minutes after showtime.” This already mirrors the estimated runtime of AMC’s preshow content, which includes ads and trailers, but now customers will be better informed if they want to arrive a little later without missing the start of thei
Introduction From fitness trackers to smart speakers, mobile sensing has quietly become ubiquitous, embedding itself into our daily lives. These devices are capable of monitoring motion, detecting presence, identifying user activities, and even inferring health conditions, sometimes without any user interaction.

Jay Dickman/Getty Images I remember when I started using Linux in the late 1990s. Back then, using the command line wasn't optional. If you worked with the open-source operating system, you had to spend time in the terminal. Using the command line in the past was challenging because there wasn't as much help as today. I was pretty much on my own. Thankfully, I struggled through and became proficient. With the help of man pages (manual pages for commands), I survived those early days. Of course
In the animal kingdom, there is incredible variation in visual perception. What an animal sees depends on the structure of its retina and its neural visual processing system. Most insects can see ultraviolet, blue and green light, but there is wide variety among arthropods; mantis shrimp eyes have up to 12 different channels of color, revealing the ultraviolet spectrum and polarized light. The ancestor of living vertebrates could likely detect red, purple, blue and green — an ability that was ma
Players who bought the Nintendo Switch 2 with the laser focus of playing Nintendo’s exclusive titles may have been disappointed that the sole first-party experience available at launch was Mario Kart World. You won’t have to sit on your hands for much longer—Donkey Kong Bananza, set to release on July 17, might just be the best reason to own a Switch 2 this early in its life cycle. I played around 2.5 hours of the upcoming game starring Nintendo’s raging gorilla, and I couldn’t stop punching at
A new report from The Hollywood Reporter alleges that Elio, Pixar’s latest movie, has become the latest in a growing line at the studio to face radical cuts and changes from senior management—including, yet again, the erasure of a queer narrative. The report revealed that Elio had a fraught behind-the-scenes production, that saw much of original director Adrian Molina’s (Coco) vision undergo significant restructuring to become the film that is in theaters now. The disappointing alterations of t
