int main()
{
int n, max = -10000000, cn;
cin >> n;
cn = n;
int y = n % 10 + (n / 100) * 10;
cn = n / 10;
if (cn > max)
{
max = cn;
}
if (n % 100 > max)
{
max = n % 100;
}
if (y > max)
{
max = y;
}
cout << max;
return 0;
}
2.
#include <iostream>
using namespace std;
int main()
{
int n, s = 0;
cin >> n;
cout << "s = ";
for (int i = 1; i <= n - 1; i++)
{
cout << i << " + ";
}
s = n*(n + 1)/2;
cout << n;
cout << endl;
cout << "s = " << s;
return 0;
}
