Скачать или смотреть 204. Count Primes | Leetcode Unlocked - Python

Learn the most efficient way to solve LeetCode 204 Count Primes using the Sieve of Eratosthenes algorithm! In this tutorial, we visualize why the naive primality test causes a Time Limit Exceeded (TLE) for large inputs and how the Sieve method optimizes execution time to O(n log log n). We walk through the logic step-by-step, explaining the boolean array setup, inner loop optimizations, and space complexity analysis. This video provides a detailed Python solution breakdown and includes full code implementations for Java, C++, and JavaScript. Perfect for mastering array manipulation and math-based coding interview questions.
