Already solved ! Classic problem of the DFS #100DaysOfCode #LeetCode #DSA

It seems like @OpenAI is down, showing a "BAD Gateway" error. Anyone else facing this issue? 🛠️

Just done with the normal brute force solution (BFS) and it was good to go. #DSA #100daysofcoding

[Dheeraj @DheerajCoder]

First tried the greedy approach done one submission wrong, then realized the correct approach but yes the question was absolutely good , give good brainstorming. #100daysofcoding #DSA

Today's question was tricky! Initially tried a visited approach: set visited to 0, checked row/col sums for 0. Worked for 1056/1058 cases. Realized the flaw, switched to precomputing positions—got it right! 🎯 #CodingJourney #ProblemSolving #DSA

🚀 Struggling with Trapping Rainwater in 2D? 🧩 Think boundaries!

1️⃣ Use a Min-Heap to process cells from the edges inward.
2️⃣ Calculate water trapped based on the smallest boundary height.

@heyshrutimishra where do u create this types of pages for the posts? please dm or replie

[Dheeraj @DheerajCoder]

🚀 Solved with 🔥 0-1 BFS!

Minimize cost by prioritizing direction matches (free moves 😎) handling changes (cost = 1 💸).

✅ Free moves 😎 + Minimal changes 💸 = Optimal path 🚀
🕒 O(m × n)

To check if a valid array exists, XOR all elements in derived. If the result is 0, you're golden! 🌟

Can't post in this week because busy in the Azure Developer Day , visited the Microsoft office gained the insights how the things works and lot more fun. Comment or dm if someone want to talk about it.😀

Xorify Question and Horrify solution , take a bit to think that how get optimuzed from t.c O(n*m) and s.c. O(1) but finally solve but the interesting part is that if the length is odd then only contribute #DSA #Programming #Coding #Problemsolved #Journey #tech

[Dheeraj @DheerajCoder]

Today was good one, brute force was easy just compare all and check that is it subset by creating the 2 frequency array , but optimized was the good one we have to pre compute the frequency. #LeetCode #DSA #DSAwithCPP #Java #problem #problem_solver #consistency

Once again the simple string problem #DSA #CodingChallenge #100DaysOfCode #simple

[Dheeraj @DheerajCoder]

Simple approach , simple question #DSA #CodingBootcamp #ProgrammersDay #DailySports

[Dheeraj @DheerajCoder]

just simple bruteforce #DSA #Coding #Programming #CodingLife

[Dheeraj @DheerajCoder]

Mostly same as the yesterdays problem , just get the sum and remove the element from it and check if it is greater than or not. #DSA #CodingJourney #ProblemSolving #DailySports #consistent

Done in the second attempt with prefix sum , first was the map #DSA #programminghelp #Coding #CodingJourney #LeetCode
