Beginner's Guide

🔥Find your solution

Press "T" in windows/mac/linux to open the file finder.
Enter your problem name. We support only following naming formats to find files! Note: We are slowly migrating to normal word spacing format for new files, see Contributing.md.
- Old questions finding
  - PascalCase (ThisIsTheExampleOfPascalCaseWritingWriting)
  - Snake case (this_is_the_example_of_snake_case_writing)
  - Caterpillar case (this-is-the-example-of-catarpillar-case-writing)
  - Normal (A question name with proper words and spacings)
  - Most of Leetcode Questions also have question numbers. Eg. 1007-minimum-domino-rotations-f...
- New questions finding
  - Normal (A question name with proper words and spacings)
  - Proper structure with folders/directories according to coding platforms.
If exists, select your solution file according to your programming language.
If your problem's solution doesn't exist
- Either create an new Issue and request public to solve it for you.(Coming soon...)
- Or Contribute it by yourself🔥
