First, let's make sure that the longest Manhattan distance is only possible for x1+y2-(X2+y2) and x1-y1-(x2-y2) so we only need to maintain four values,Represents Max (X+y), respectively; Max (x-y); Min (x+y); Min (x-y);So the answer is Max (max (x+y)-min (x+y), Max (x-y)-min (x-y).1 Constmaxn=3000000;2 varMaxadd,minadd,maxdec,mindec,i,a,b,n:longint;3 function Max (a,b:longint): Longint;4 begin5 ifA>B then exit (a)6 Elseexit (b);7 end;8 function min (a,b:longint): Longint;9 beginTen ifaB

In recursive mode, the ox is divided into two types to find the corresponding relationship.
Today, I suddenly found that such a question is also DP. I used to think that it is a regular expression or something.
To sum up the two DP questions we have encountered, the recurrence of DP is based on the timeline and path line, and the results are classified. These
