[@user-pv4xn3sg7j]

Missed your daily videos bro.

[@runabishek]

Please don't skip posting videos😅

[@dingus2332]

To be fair , questions asked in that time frame , were not that deep

[@surajmandal_567]

Let's write some more neetcode 🎉.

[@tekfoonlim4745]

I use subtitles always.. and it gives let's write some neat code 😂😂

[@MP-ny3ep]

Great explanation as always. Thank you very much.

[@shashankgupta5192]

Finally you are back!!❤

[@aksharpathak5226]

thanks bro for uploading the video.......I thought you stopped solving leetcode

[@rahulchauhan.]

One can adapt this problem to find the maximum falling path too!

[@ahmedtremo]

Welcome back :D

[@mrgeorgy93]

I got my Amazon offer yesterday, largerly thanks to your channel!

[@NeetCodeIO]

HAPPY FOR YOU ❤️🚀🔥

[@LeetCodeUzbekistan]

bro in the moring I looked for your video, I could solve this by my own and then you publishing this video which is the exact same algorithm 😅

[@dumbfailurekms]

sometimes u are literally the only light in my eternal dark hell

[@Dancedfsk8]

Finally!

[@Pegasus02Kr]

Is it truly a solution for medium difficulty problem? was much harder to understand than most of hard problem for me..

[@imretakacs8952]

At line 8, should not that be c >= 0 instead of c > 0.

[@justintang6313]

Is the DP solution top-down or bottom-up?

[@Itachi-mr8nj]

Bro is gonna pretend like he didn't go missing for a few days

[@alviahmed7388]

When will you stream next?

[@mikerico6175]

Could do += line 10 and use inf instead of float(“inf”)

[@phatboislym]

what is "line 10"?

[@mikerico6175]

@@phatboislymmatrix[r][c] = matrix[r][c] + …. instead just do matrix[r][c] +=

[@user-vs1jd4kp4h]

@@phatboislym you can avoid by managing index inside the indexing as well like this: I used extra dp matrix but you can use the same input array to do this as well def minFallingPathSum(self, matrix: List[List[int]]) -> int: m, n = len(matrix), len(matrix[0]) dp = [[0 for _ in range(n)] for _ in range( m+1)] for i in range(m-1, -1, -1): for j in range(n): dp[i][j] =min(matrix[i][j]+dp[i+1][max(0,j-1)], matrix[i][j]+dp[i+1][j], matrix[i][j]+ dp[i+1][min(n-1,j+1)]) return min(dp[0])

[@XEQUTE]

Please do daily neetcode problems or update the community posts with links to earlier solved problems please I do not want to watch any other channel

[@NeetCodeIO]

Sure, will do!

[@user-sj1fk4vs3n]

why i am getting tle??? class Solution { public int minFallingPathSum(int[][] matrix) { int n=matrix.length,m=matrix[0].length; int min=Integer.MAX_VALUE; int dp[][]=new int[n][m]; for(int row[]:dp) { Arrays.fill(row,-1); } for(int i=0;i

[@elyababakova2125]

A nice problem to revise classic DP solutions. Thanks for video, I was missing your daily solutions! BTW @NeetCodeIO, I wonder wether you've bought a leetcode T-Shirt for leetcoins? :)

[@aksimsons]

Anyone getting TLE for running recursive solution in Java? This is my code:- class Solution { public int dfs(int row,int column,int[][] matrix,HashMap s){ int n=matrix.length; if(row==n ) return 0; if(column==n || column
