How to print this pattern? can anyone explain logic?

Question

Star pattern

Anyone can make logic for this pattern? I tried using 2 for loops also. I just had an interview where I was asked to create star pattern as shown in picture.

#include <stdio.h>
int main()
{
   char f;
    int n;
    printf("Enter the number:");
    scanf("%d", &n);
    int i, j, s, k, l, m;
    for (s = 1; s <= n; s++) //printing
    {
        for (k = 1; k <= n; k++)
        {
            for (i = 1; i <= n; i++) //pattern
            {
                for (j = 1; j <= n; j++)
                {
                    if ((i + j == n + 1)) //star positions
                    {
                        printf("* ");
                    }
                    else
                    {
                        printf(" ");
                    }                
                }
                printf("\n");   //next line
            }            
        }        
    }
    return 0;
}

This problem can solve using 2 for loop.

#include<stdio.h>
    int main()
    {
        int num;
        printf("Enter pattern length :");
        scanf("%d",&num);
        
        int matrix=num*num;
        for(int i=0;i<matrix;i++)
        {
    
            for(int j=0;j<matrix;j++)
            {
               if((i+j+1)%num==0)
               {
                   printf("*");
               }
               else
               {
                  printf(" ");
               }
            }
            printf("\n");
        }
    }
