30 Dias de Código

30 Days of Code

en pt-br

This project consists of a series of 30 LeetCode questions, accompanied by videos where we discuss the solutions to these questions. The goal is to provide a solid preparation for interviews at major technology companies, covering asymptotic analysis and performance trade-offs.

How to Use

Each day of the challenge corresponds to a file, numbered by date. Inside each exercise, you will find the solution code in C++, along with asymptotic analysis and performance trade-offs.

You can find the solution videos here -> HTGO

  1. Find Eventual Safe States
  2. Missing Number
  3. Valid Anagram
  4. Intersection Of Two Linked Lists
  5. Group Anagrams
  6. Inorder Traversal
  7. First Bad Version
  8. Insert Delete Get Random
  9. Candy
  10. Construct K palindrome Strings
