这道题样例过了,但是为什么是0分,还超时了?
错误代码:(要修改!)

@王子耀 能帮我看一下吗?

for(int j=i;j<=5000000;j+=i){
s[j]+=i;
}
}
for(int i=1;i<=t;i++){
scanf("%d",&n);
printf ("%d\n",s[n]);
}
return 0;
这是我写的核心
建议再加上火车头,不然容易超时

你应该先预处理,用双重循环:
for(int i=1;i<=5000000;i++){
for(int j=i;j<=5000000;j+=i){
s[j]+=i;
}
}
s[j]:j的约束和
最后每次输出就OK了。

我的70分代码,你看看有没有思路,要是有跟我说一下,我也不会🤓
