Possible disadvantages

    LeetCode mainly focuses on algorithm and data structure problems and doesn't cover other technical aspects like system design, databases, or front-end development as comprehensively.
  • Variable Quality of Community Solutions
    While the community is active, the quality of user-contributed solutions and explanations can vary significantly, and some may not follow best practices or be optimal.
  • Platform Performance Issues
    Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.
