PrinceSinghhub / 22 Key DSA Patterns with Must-Solve Problems! 💡.md
Last active September 10, 2025 13:09
After solving and observing many interview problems, I’ve identified key patterns that will help you solve them.

Problem-Solving Techniques and Patterns

1. Fast and Slow Pointer

Description: This technique uses two pointers moving at different speeds to solve problems involving cycles, such as finding the middle of a list, detecting loops, or checking for palindromes.

  • Linked List Cycle II
  • Remove nth Node from the End of List
  • Find the Duplicate Number
  • Palindrome Linked List

const SHOW_SIDES = false; // color sides of DOM nodes?
const COLOR_SURFACE = true; // color tops of DOM nodes?
const COLOR_RANDOM = false; // randomise color?
const COLOR_HUE = 190; // hue in HSL (https://hslpicker.com)
const MAX_ROTATION = 180; // set to 360 to rotate all the way round
const THICKNESS = 20; // thickness of layers
const DISTANCE = 10000; // ¯\\_(ツ)_/¯
