• Java Solutions for the Neetcode.io practice problems.

• This repository includes different coding patterns, which have been separated out as Java packages.

  • For example, a program for "Two Pointers" pattern can be found in the package com.pallamsetty.twopointers

• Unit tests are used to test the solution for each problem with different inputs.

• In some cases, where I have attempted multiple solutions, I have used the same inputs for all the solutions.

• Further, I have added the corresponding Leetcode problem number for the same problem wherever possible.

• To skip to the particular pattern:

  • Arrays & Hashing
  • Two Pointers
  • Sliding Window
  • Stack
  • Binary Search
  • Linked List
  • Trees

• Unit tests can be found at:
