hello @mohitsingh

have u seen previous videos?

for this problem observe this->
since each rows and colums are sorted in ascending order , the largest value of matrix will be at the bottom right corner, similary all higher values will be found near that corner.
thats the reason we have fixed one corner of the required submatrix at bottom right and then looking for top left corner of required matrix
