    for (i = 0; i < n; i++)
    {
    
        for (j = 0; j <= i; j++)
        {
    
            printf("*");

        printf("\n");
    }
    for (i = 0; i < n; i++)
    {
    
        for (s = 0; s < i; s++)
        {
    
            printf(" ");
        }
        for (j = 0; j < n - i; j++)
        {
    
            printf("*");
