rt，我输出五倍WA了，是不是n+n+n+n+n有问题

#include<bits/stdc++.h>

using namespace std;

inline int read(){
    int ret=0;char c=getchar();
    while(c<'0'||c>'9') c=getchar();
    while(c>='0'&&c<='9') ret=(ret<<3)+(ret<<1)+c-'0',c=getchar();
    return ret;
}
void write(int x){
    if(x>9) write(x/10);
    putchar(x%10+'0');
}

int main()
{
    int n=read();
    write(n+n+n+n+n);puts("");
    return 0;
}
