C :

#include <stdio.h>

int main(void) {
	int i, n, s = 0;
	do
		scanf("%d", &n);
	while(!(n >= 0 && n <= 9));
	for(i = 1; i <= n; i ++)
		s += i * 11;
	printf("%d", s);
	return 0; 
}

C++ :

#include<cstdio>
using namespace std;
int main()
{
	int i,n,s=0;
	scanf("%d",&n);
	for(i=1;i<=n;i++)
	{
		s=s+i*11;
	}
	printf("%d",s);
	return 0;
}

Pascal :

var i,a,s:integer;
begin s:=0;
 read(a);
 for i:=1 to a do
 s:=i*11+s; writeln(s)
end.
