LeetCode
A mainstream online platform for algorithmic problem practice, providing exercises covering data structures and algorithms. Problems are categorized into Easy, Medium, and Hard tiers, and the platform is widely used as a core preparation tool for technical interviews at major technology companies.

Timeline (last 90 days)
Advent of Code and LeetCode are algorithm and puzzle activity platforms that can be used for recreational programming.
The retreat of the grinding culture is more likely an adjustment in evaluation weighting rather than a complete disappearance.
The correlation between the ability to solve coding problems and actual engineering competence has long been a subject of debate.
The LeetCode platform was founded around 2015, integrating scattered interview questions into a structured question bank and providing an online judging function.
The phrase "Sorry we made you grind LeetCode" recently sparked widespread discussion in the tech community on Hacker News.
Relying solely on grinding algorithmic problems as the only interview preparation strategy is becoming ineffective, as companies are shifting their assessment focus toward actual engineering construction ability and judgment.
LeetCode was founded in 2011 and primarily serves technical interview preparation
LeetCode was founded in 2011, shifted its focus toward technical interview preparation, and its problem library emphasizes data structures and algorithms.
TopCoder was founded in 1997, LeetCode was established in 2011, HackerRank was established in 2011, and Codewars was established in 2012.
LiveCodeBench continuously scrapes new problems from competitive programming platforms such as LeetCode, Codeforces, and AtCoder to prevent data contamination.
