Why we ddint do start_row<end_row in the while loop?

#1

would it work for both columns and rows ?? couldnt understand this last case

#2

@manthan.joshi.jiit which time stamp?

#3

the last edge case where he tells that if row is odd then it would skip the middle one …does the same happens with the columns?? time stamp is 13:36

#4

@manthan.joshi.jiit it will work fine
