Day 3/30 of #30DaysOfDSA π
Started the Arrays module of #NamasteDSA today.
β’ Time & Space Complexity
β’ Remove Duplicates from an Array
Starting to think beyond just getting the code to work, understanding how efficiently it works too.

Starting from Zero β Intermediate π»
Daily learning + problem solving, with progress shared on GitHub & X.
Letβs begin! π₯

Graph BFS and DFS Traversals
Before I approach LeetCode graph problems, I have to familiarise myself with useful graph operations.
I'll continue with this tomorrow and proceed to LeetCode afterwards
Day 20 of #30DaysOfDSA
Construct a Binary Tree from Preorder and Inorder Traversal
Took me HOURS.
This wasn't medium in any way, shape, or form.
I'll solve some more tree problems today and move on to Graphs tomorrow.
Day 19 of #30DaysOfDSA
Problem: Unique Binary Search Trees
Couldn't solve this completely myself because I failed to realize the properties of a Binary "Search" Tree.
But now I get it.
Day 17 of #30DaysOfDSA
Problem: N-ary Tree Preorder Traversal
Was pretty nice solving this, just had to get past the bad leetcode descriptions.
This would be my last stack problem. On to Trees
Day 16 of #30DaysOfDSA
Problem: Min Stack
Well, once I understood that getMin() wasn't actually removing the min.
It wasn't too bad to implement all O(1) time functions
Day 14 of #30DaysOfDSA
Actually, scrap that, I came up with something faster.
The first solution helped me realize this is just a sum of products
So I did it in one pass, constant memory
Day 13 of #30DaysofDSA (Part 2 lol)
Wow, this is getting hard.
Calculators are kinda difficult because of the order of operations
Day 13 of #30DaysOfDSA
Problem: Basic Calculator 2

Day 13 of #30DaysOfDSA
Problem: Basic Calculator 2
Day 12 of #30DaysOfDSA
Problem: Simplify Path
Pretty easy problem served as a nice intro to using stacks.
Today π , I am starting a 30 days challenge series where i will be solving 1 leetcode problem every single day for 30 days in java to maintain my consistency πͺ .
π Day 1 /30 of #30DaysofDSA | problem : Merge Sorted array (LC #88)
#DSA #JAVA #LeetCode #30DaysofDSA #CHALLENGE
Day 11 of #30DaysOfDSA
Problem: Compare Version Numbers
This was fairly straightforward tbh
I'm comfortable with two pointers now, moving on to stacks
Unfortunately, there is no native Queue data structure in JS.
Day 10 of #30DaysOfDSA
Problem: Sort Colors
Perfect example of a medium 2-pointer problem.
Honestly, didn't think one pass was possible, but here we are.
Day 6 of #30DaysOfDSA
Sorting.
1. 2.. 3...
Revisited all the popular sorting algorithms and noted each of their time complexities.
Most interesting is how insertion sort can go from O(n^2) to O(n) depending on the array π
