## Discussion of Problem 1231. Turing: One, Two, Three, …

A few questions(+)
Posted by Maigo Akisame (maigoakisame@yahoo.com.cn) 31 Oct 2004 03:55
1.The prob says we can only place '+','#','A'..'Z' on the tape. So can't we place '-'? But the sample output places '-'!
2.What's the range for condition?

So I don't understand why my prog gets WA:
program ural1231;
const
maxn=200;
var
remain:array[1..maxn]of byte;
k,i:byte;
begin
remain[1]:=1;
for i:=2 to maxn do begin
remain[i]:=(remain[i-1]+k) mod i;
if remain[i]=0 then remain[i]:=i;
end;

writeln('1 # 1 # >');
for i:=1 to maxn do
writeln(i,' - ',i+1,' + >');
for i:=1 to maxn do
writeln(i+1,' # ',1000+i-remain[i],' # <');
for i:=1 to maxn do
writeln(1000+i,' + ',999+i,' + <');
writeln('1000 + 1000 - =');
end.

1. I don't know why can't you place "-", but you needn't do it.
2. I believe -/+ MAXINT32. Mine solution used condition like 100001
3. Your prog doesn't output the number of lines of the control table.
