Can you give me some test?
var
x1,x2,mink,minx,i,j,abcx:integer;
n,m:integer;
s,min,k:longint;
num:array[0..500]of longint;
costv:array[1..500]of longint;
f:array[0..100,1..500]of longint;
prec:array[1..100,1..500]of integer;
wri:array[1..50000]of integer;
begin
readln(n,m);
fillchar(f,sizeof(f),0);
for i:=1 to n do
begin
fillchar(num,sizeof(num),0);
for j:=1 to m do read(costv[j]);
for j:=1 to m do num[j]:=num[j-1]+costv[j];
for j:=1 to m do
begin
min:=maxlongint; mink:=j;
for k:=1 to m do
begin
if j<k then s:=num[k]-num[j-1]+f[i-1,k]else
s:=num[j]-num[k-1]+f[i-1,k];
if s<min then begin min:=s; mink:=k;end;
end;
f[i,j]:=min; prec[i,j]:=mink;
end;
readln;
end;
min:=f[n,1];minx:=1;
for i:=1 to m do
begin
if f[n,i]<min then begin min:=f[n,i];minx:=i;end;
end;
x1:=n;x2:=minx;
k:=0;
while x1<>0 do
begin
inc(k);
wri[k]:=x2;
if x2<>prec[x1,x2] then
begin
for abcx:=x2+1 to prec[x1,x2] do begin inc(k);wri[k]:=abcx;end;
for abcx:=prec[x1,x2] to x2-1 do begin inc(k);wri[k]:=abcx;end;
end;
x2:=prec[x1,x2]; dec(x1);
end;
for i:=k downto 1 do writeln(wri[i]);
close(input);
end.
I don't know why WA at Test 5.Who can give me some tests?
