        for(int j=1;j<=i;j++)
        {
            ans+=i;
            l++;
        }
        if(k==l)
        {
            cout<<ans;
            return 0;
        }

改成

        for(int j=1;j<=i;j++)
        {
            ans+=i;
            l++;
            if(k==l)
            {
               cout<<ans;
               return 0;
            }
        }

@dead_X 这么臭的优化有用的必要吗（恼

by lnwsh @ 2020-08-25 13:45:28
