Source code:

#include<stdio.h>
int main()
{
  int n;

  printf("Enter n value: ");
  scanf("%d",&n);

  int len = 2*n-1;
  for(int row=0; row<len; row++)
  {
    for(int col=0; col<len; col++)
    {
      int min = row<col? row:col;
      min=min<len-row? min:len-row-1;
      min=min<len-col? min:len-col-1;
      printf("%d ",n-min);
    }

    printf("\n");
  }

  return 0;
}
