CodeForces Day 90: Antimedian Deletion & Mickey Mouse Constructive

𝐃𝐚𝐲 𝟗𝟐/𝟏𝟎𝟎 – Competitive Programming (CodeForces) Solved: 977C - Less or Equal, 1872D - Plus Minus Permutation --977C was simple greedy: sort the array and check the k-th position carefully to satisfy the condition. --1872D was more math + greedy: instead of building permutation, count multiples using LCM, assign largest values to x-multiples and smallest to y-multiples, then compute score. #Codeforces #CompetitiveProgramming #100DaysOfCode #Greedy #Math #NumberTheory #ProblemSolving #DSA #Cpp #Algorithms

Solved a Gray Code problem in C++ today. The task was to generate bit patterns from 0 to 2^n - 1 such that every consecutive pattern differs by only one bit, while always starting from 0. I used the Gray code formula: gray = i ^ (i >> 1) This makes the solution clean and efficient, and guarantees that adjacent codes differ by exactly one bit. Example for n = 2: 00 -> 01 -> 11 -> 10 What I like about this problem is how a simple bit manipulation formula can solve what looks like a complex sequence-generation challenge.

💡 DP (Dynamic Programming) becomes simple with the right problem — Counting Bits (LeetCode 338) 👉 dp is using previous results to compute new results Instead of recomputing, just reuse:   `bits[i] = bits[i >> 1] + (i & 1)` Same patterns. Less work. Faster solution. #DynamicProgramming #LeetCode #DSA #CodingInterview #ProblemSolving #BitManipulation

Rust's borrow checker isn't the hard part. The hard part is unlearning every shortcut you got away with in other languages. No more "I'll just clone it." No more "this pointer is definitely still valid." No more silent data races. Rust doesn't trust you. After years of C++ bugs — honestly, fair. #Rust #Programming #SoftwareEngineering #SystemsProgramming #DevLife

RevelCode is the intuitive programming language built for engineers and operators alike, designing out common mistakes from the ground up so your control logic is inherently failsafe. Listen to the full segment with Scott Morton on TBPN - link in comments.

rust 1.95.0 released ✅ cfg_select! is now built-in: Say goodbye to dependency bloat. This new macro provides a native way to handle conditional compilation with a clean, match-like syntax. It’s essentially a built-in version of the popular cfg-if crate. ✅ if let guards in matches: We finally have more power in match arms! You can now use if let patterns as guards, allowing you to bind variables and check conditions simultaneously within a single match arm. No more nested "if" soup. ✅ Fixing the "Range" Mistake: For years, the fact that Range didn't implement Copy was considered a core design regret. 1.95.0 introduces core::range::RangeInclusive, a major step toward a modern, copyable range system that will eventually become the default in Edition 2027. https://lnkd.in/ddtBn_R8 #RustLang #Programming #SoftwareEngineering #OpenSource #CodingUpdate #Rust195

Stop memorizing Rust rules. Start deriving them. 🦀 This free interactive course reframes the borrow checker not as a set of rules to memorize, but as the logical outcome of three primitives: Space, Time, and Coordinates. 📐 Every memory bug is just a failure in one of these three dimensions: 🔸 Use-after-free 🔸 Dangling pointer 🔸 Data race 🔍 Understand the framework, and the compiler's behavior clicks into place. ✅ 💡 Highly recommended for experienced devs, especially those with a C/C++ background. 👇 https://lnkd.in/gAsQvjhv #Rust #RustLang #Programming #SystemsProgramming #SoftwareEngineering

Replacing C++ with RUST might not be a good idea as C++ is stepping into a new era with a powerful framework designed to express and control concurrency and parallelism more intuitively. At its core, the model introduces three key abstractions: schedulers, senders, and receivers. These components work together seamlessly, enabling developers to compose flexible and customizable asynchronous workflows. What makes this especially exciting is how naturally it integrates with C++20 coroutines. This combination simplifies the process of writing structured concurrency, where lifetimes are cleanly nested and easier to reason about. The result? Programs that are safer by design and inherently resistant to data races. It’s not just about performance anymore—it’s about correctness and clarity at scale. Even more promising, major compilers like GCC and Clang are already ahead of the curve. They’ve implemented a significant portion of upcoming C++26 features during the standardization phase. The future of modern C++ is arriving faster than expected—and it’s built for safer, smarter parallelism. #C++2026 #OOP #Programming
