🚀 Linked List Progress!

Today I practiced multiple Linked List problems on LeetCode and learned:
🔹 Rearranging nodes
🔹 Detecting Linked List Cycle
🔹 Deleting nodes
🔹 Tortoise & Hare approach 🐢🐇
🔹 Solved problems using the concepts I learned

#DSA #LinkedList #LeetCode

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I learned how to insert an element at the head and at a specific position in a Linked List. 🔗

Also solved a LeetCode problem and understood the code step-by-step.

Another solid step forward in DSA! 🚀

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I revised Linked List concepts in DSA. 🚀

Learned:
• Data & Nodes
• Traversal method
• Insert method
• Append method

Also solved a Linked List problem on LeetCode. 💻

Slowly building stronger DSA fundamentals every day. 🔥

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I learned the basics of Linked Lists in DSA. 🚀

• Difference between Array, List & Linked List
• Linked List as a Data Structure
• Understanding Nodes and their structure
• Data + Next (reference/address)
• How "next" connects one node to the next in memory

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I solved First & Last Occurrence using Lower Bound & Upper Bound with Binary Search. 🔍

Learned how Lower & Upper Bound can be used to find exact positions efficiently.

O(log n) 🚀

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I learned Floor & Ceil using Binary Search 🚀

Understood how to find the largest element smaller than or equal to the target (Floor) and the smallest element greater than or equal to the target (Ceil) with Time complexity

[Navdeesh Bhatia @BhatiaNavdeesh]

Today’s DSA progress 🚀

• Learned Lower Bound & Upper Bound
• Implemented both using Binary Search
• Solved InterviewBit questions
• Solved a LeetCode problem

Slowly building strong DSA fundamentals every day. 💻🔥

Today I learned Binary Search 🔍

I understood how we divide the search space into half, compare the middle element, and decide which half to search next. Also learned how Binary Search can be implemented using recursion.

Time Complexity: O(log n) 🚀

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I solved the 3Sum problem and learned a better approach with O(n²) time complexity.

I also learned how to use sets with tuples, why lists are not hashable, and how sorting helps us build a more optimized solution.

Small improvement, but a big learning! 🚀

#DSA #Python

[Navdeesh Bhatia @BhatiaNavdeesh]

While solving the 3- Sum problem I learned a new Python concept

I found out that a list cannot be added to a set because lists are not hashable. But tuples are hashable, so after sorting the array, I can convert the result into a tuple and store it in a set to avoid duplicate.

[Navdeesh Bhatia @BhatiaNavdeesh]

Today I solved the Maximum Non-Negative Subarray problem on LeetCode and learned how to handle continuous subarrays using a running sum.

Concepts I practiced:
• Array traversal
• Subarrays
• Running sum
• Maximum sum tracking
• Handling negative elements

[Navdeesh Bhatia @BhatiaNavdeesh]

Today’s DSA progress 🚀
