Question

Could someone help implement this in python. Would be great to show it for local max too. Just trying to achieve O(n) complexity.

 
Algorithm 2: Divide And Conquer Approach
Data: N: Length of the matrix side
M: The NxN matrix
Result: Returns a local minimum in the given matrix M
Function Find_Local_Minimum(Matrix M):
middle_rowt
M.length .
middle_coluтп +
M[1].length.
min_cell +
Min(Get Min In Row(middle_row), Get Min_In Column(middle_column));
next_cell + Get_Next Cell(min_cell);
if next_cell = min_cell then
| return min_cell;
end
else if next_cell.row < middle_row then
if next cell.column < middle_column then
return Find Local Minimum(Top-Left Sub-Matrix);
end
else
return Find Local Minimum(Top-Right Sub-Matrix);
end
end
else
if next cell.column < middle_column then
return Find_Local_Minimum(Bottom-Left
Sub-Matrix);
end
else
return Find Local Minimum(Bottom-Right
Sub-Matrix);
end
end
