int i, j, k, num = 5;
cout << "number u1=";


cin >> num;
for (i = 1; i <= num; i++)
{
for (j = 1; j <= num - i; j++)
{
cout << " ";
}
for (k = 1; k < i; k++)
{
cout << k;

}
for (k = i; k >= 1; k--)
{
cout << k;
}

cout << endl;
}

//----------------------------------------
for (i = num; i >= 1; i--)
{
for (j = 1; j <= num - i; j++)
{
cout << " ";
}
for (k = 1; k < i; k++)
