DSA-Practice

This repository contains all the coding problems solved by me.

  • Find all topic wise questions in different folders:)
  • From Basic to Hard level questions under each topic
  • Problems are from Leetcode and Geeksforgeeks website.
  • Separate folders for CP. All Solutions are not optimised

Set O(logn) O(logn) - O(logn) O(n)
Unordered Set O(1)Average O(n)Worst O(1)Average O(n)Worst - O(1)Average O(n)Worst O(n)
Map O(logn) O(logn) - O(logn) O(n)
Unordered Map O(1)Average O(n)Worst O(1)Average O(n)Worst - O(1)Average O(n)Worst O(n)
Stack O(1) O(1) O(n) O(n) O(n)
Queue O(1) O(1) O(n) O(n) O(n)
Binary Search Tree O(log n) O(log n) O(log n) O(log n) O(n)
Binary Min Heap O(log n) O(log n) O(1) O(n) O(n)
