Answer 1

1、
var
i,sum,n:longint;
begin
readln(n);
sum:=1;
for i:=1 to n do
sum:=sum*i;
writeln(sum);
end.
2、
var
f:array[1..10000] of boolean;
i,n,sum:longint;
begin
readln(n);
fillchar(f,sizeof(f),true);
for i:=2 to trunc(sqrt(n)) do
for j:=2 to n div i do
f[i*j]:=false;
sum:=0;
for i:=1 to n do
if f[i] then inc(sum,f[i]);
writeln(sum);
end.
时间匆忙,没有编译,自己看看吧
