Given the matrix a, return the index r of the row with the most nonzero elements. Assume there will always be exactly one row that matches this criterion.
Example:
Input a = [ 1 2 0 0 0
0 0 5 0 0
2 7 0 0 0
0 6 9 3 3 ]
Output r is 4

How am I wrong here?
"a = [ ...
1 0 0;
0 0 0;
0 0 0;
0 0 0;
0 2 3];
r_correct = 5;"
My code says 2, I think it's correct, what am I missing?
It wants the number of the row with the most nonzeros.
Thank you Tim! I feel like a fool, but that'll teach me to read the requirements more carefully. Hopefully.
Great Problem!
nice
Love this one
Piece of cake
nice
easy :) but nice
Could you please check my solution.
How come the solution example 2, 3 and 4 have r= 3, 5 and 4. When it should have been r = 4, 3 and 1.
As these are the maximum number of zeros in any of the given row.
Can someone please give me a hint on how the solutions are provided so different?
What are these matrices in last 3 test cases? Can someone help
