兄弟们,为什么ans和sum不能开long long,int就行?大佬求解 longlong代码:(错的,不要复制)
#include <iostream> #include <bits/stdc++.h> using namespace std; const int N=1e7+10; const int INF=0x3f3f3f3f; int main() { int n; long long sum=1,ans; cin>>n; for(int i=1;i<=n;i++) { for(int j=1;j<=i;j++) { sum*=j; } ans+=sum; sum=1; } cout<<ans; }
int代码:
#include <iostream> #include <bits/stdc++.h> using namespace std; const int N=1e7+10; const int INF=0x3f3f3f3f; int main() { int n; int sum=1,ans; cin>>n; for(int i=1;i<=n;i++) { for(int j=1;j<=i;j++) { sum*=j; } ans+=sum; sum=1; } cout<<ans; }

#include<iostream> using namespace std; int n,ans,jc=1; int main(){
cin >> n; for(int i = 1;i <= n;i++) { jc = 1; for(int j = 1;j <=i;j++) { jc*=j; } ans +=jc; } cout<<ans; return 0;
}

#include <iostream> #include <iomanip> using namespace std; int main() { int n,sum=0,m=1; cin>>n; for(int i=1; i<=n; i++)//常用i,j,k { m*=i; sum+=m; } cout<<sum; return 0; }
