LeetCode Solutions Repository

This repository contains solutions for various LeetCode problems written in C++. Each file corresponds to a specific problem and is named following the format leetcode_<problem_number>.cpp. Below is the list of problems solved in this repository:

Problems Solved

  1. Two Sum (leetcode_1.cpp)
    The classic problem of finding two numbers in an array that add up to a specific target.

  2. Add Two Numbers (leetcode_2.cpp)
    Solving addition of two numbers represented as linked lists.

  3. Longest Substring Without Repeating Characters (leetcode_3.cpp)
    Find the length of the longest substring with unique characters.

  4. Median of Two Sorted Arrays (leetcode_4.cpp)
    A challenging problem involving finding the median of two sorted arrays.

  5. Longest Palindromic Substring (leetcode_5.cpp)
    Determine the longest substring that is a palindrome.

  6. Zigzag Conversion (leetcode_6.cpp)
    Reformat a string in a zigzag pattern for given rows.

  7. Reverse Integer (leetcode_7.cpp)
    Reverse the digits of an integer while considering integer overflow.

  8. String to Integer (atoi) (leetcode_8.cpp)
    Implement the atoi function that converts a string to an integer.

  9. Palindrome Number (leetcode_9.cpp)
    Check if a given integer is a palindrome.

  10. Regular Expression Matching (leetcode_10.cpp)
    Solve pattern matching using regular expressions. (Needs review; revisit)

Notes

  • The solutions aim to be clear and efficient, using optimal algorithms and data structures where possible.
  • The Regular Expression Matching problem is flagged as "watch it again," indicating it may require further review or study.

How to Run

To compile and run a specific solution:

g++ -std=c++17 -o solution leetcode_<problem_number>.cpp
./solution

Replace <problem_number> with the desired problem number (e.g., 1, 2, etc.).
