哪位哥哥教教我

我不知道什么压缩 什么排序

只是用了动规

var

i,j,p,q,l,s,x,t,m,v:integer;

a,f:array[-10..1000000000] of 0..1;

jl:array[1..100] of integer;

begin

fillchar(f,sizeof(f),0);

fillchar(a,sizeof(a),0);

readln(l);

readln(s,t,m);

for i:=1 to m do

begin

read(x);

a[x]:=1;

end;

for i:=s to t do

if a[i]=1 then f[i]:=f[i]+1;

v:=0;

while v

    const maxl=4000; maxm=100;……

    const

    maxl=4000;

    maxm=100;

    var

    l,i,j,ans:longint;

    s,t,m:byte;

    stone:array[0..maxm+1] of longint;

    b:array[1..maxl] of byte;

    f:array[-10..maxl] of longint;

    procedure swap(var a,b:longint);

    var c:longint;

    begin

    c:=a;a:=b;b:=c;

    end;

    function min(a,b:longint):longint;

    begin

    if astone[j]

    then swap(stone[i],stone[j]);

    stone[0]:=0;stone[m+1]:=l;

    for i:=1 to m+1 do

    if stone[i]-stone>90

    then stone[i]:=stone+(stone[i]-stone) mod 90;

    l:=stone[m+1];

    fillchar(b,sizeof(b),0);

    for i:=1 to m do

    b[stone[i]]:=1;

    for i:=-10 to 0 do

    f[i]:=0;

    for i:=1 to l+t do

    ans:=maxint;

    for i:=l to l+t do

    ans:=min(ans,f[i]);

    writeln(ans);

    end.

    路径压缩

    有很多连续的0可以证明是没用的,自己想想怎么压吧。
