I got this in an interview and I bombed. I wish I had seen this video earlier ..Beautifully explained..

[tusharvengurlekar]

One of the excellent algorithm series so far. Well explained each example with diagrams. Good job.

[santanu]

I needed that first hint then I got the algorithm. Thank you

[ajaib]

SUCH A BEAUTIFUL EXPLANATION, THANK YOU!

[JSDev]

instead of moving 1 cell at a time can we do some kind of binary search to discard multiple row/collums at once and further optimize this?

[autoot]

Best explanation of the search space reduction solution! Thanks for sharing.

[VikashSingh-ufqr]

Really like this approach and explaination

[crisag.]

Your explanations are amazing! Thank you for making these videos.

Just amazing explanation, now words.... and the best thing is visualisation,

[abheermehrotra]

why is c = matrix[0].length ? why we have written 0 ??

[realAB]

Excellent explanation...Please continue making these kind of videos.

[anvesh]

At first i applied binary search on each row which has n logm complexity. Now found very optimal method.

[Nikita-hvjm]

bext explanation....keep it up and thanks a lot

[karanmandveb-]

I think time complexity would be O(n*m) in worst case

[amitupadhyay]

Why dont I come with such awsome tricks : (

[himanshupal]

You didn't tell why we can't start from (0, 0) and (n - 1, m - 1)????
