Answer 1

#include <stdio.h> 
  
int main(void)
{   
    int space, rows = 5, count = 0, j = 0, n = 0;

    for(int i = 1; i <= rows; i++)
    {
        for(space = 1; space <= rows - i; space++)
        {
            printf("  ");
            count++;
        }

        while(j != 2 * i - 1)
        {
            if (count <= rows - 1)
            {
                printf("%d ", i + j);
                count++;
            }
            else
            {
                n++;
                printf("%d ", (i + j -2 * n));
            }
            j++;
        }
        n = count = j = 0;

        printf("\n");
    }
     
    return 0;
}
