表接好

8L~17L好顶赞！
附标准解法：
var n,i,ans:longint;s:string;
begin
readln(n);
readln(s);
ans:=0;
for i:=1 to n do
ans:=ans*2+ord(s[i])-48;
writeln(ans);
end.

Pascal居然没有 strtol 这么方便的东西？

七楼的，打表干什么啊？乘权求和就行了，有时候打表会要注意各种技术性问题的。

var k,a,i,m:longint;
n,s,s1,s2:string;
c:array[1..999] of longint;
begin
readln(s1);
for i:=1 to length(s1) do if s1[i]=' ' then break;
n:=copy(s1,1,i-1);
s2:=copy(s1,i+1,length(s1));
val(s2,m);
s:=n;
for i:=length(s) downto 1 do if ord(s[i])-58<=0 then c[length(s)-i+1]:=ord(s[i])-48
else c[length(s)-i+1]:=ord(s[i])-55;
for i:=1 to length(s) do if c[i]<>0 then for a:=1 to i-1 do c[i]:=c[i]*m;
for i:=1 to length(s) do k:=k+c[i];
writeln(k);
end.

…………………………
简单的来了
var a,b,c,d,e，i
:longint;
type atype=1...10;
begin
c:=1;
readln(a);
d:=a;
e:=a;
i:=0;
for i:=1 to a do begin
write(b);
repeat c:=c*2;
d:=d-1;
until d=1;
b:=b*c;
e:=e-1;
d:=e;
i:=i+b;
end;
writeln(i);
end.

则么样
