At 8:34 what is end?

Is he talking about end of row or end means (bi,bj) ???

seriously whole this topic is poorly explained, need some better faculty to explain it. Please do not change faculties.
I enrolled because of Prateek Bhai. I do not want to disrespect this faculty but Prateek Bhai is better at explaining topics.

Hope you understand.

@premang
if our matrix is n*m (i.e n rows and m column) then end (in the video) corresponds to last index of row and last index of column.

@premang
for example
if matrix is 4 X 5
then for top left corner (i,j)
i and j will be as follows
i -> 0 to 3
j -> 0 to 4

I hope I’ve cleared your doubt. I ask you to please rate your experience here
