    This worked for me

    #include <stdio.h>

int main() 
{    
    int n,total; //total number of rows and columns
    scanf("%d", &n);
    total=n*2-1;
    for(int row=0;row<total;row++) {
        for(int col=1;col<=total;col++){
            if(row>total/2&&row<total-1){ //second half pattern
                if(row+col<total && col<total/2 )
                    printf("%d",n--);
                else if(col>row+1&&row<total-1)
                    printf("%d",++n);
                else 
                    printf("%d",n);
            }
            else if(col<=row&&row<=total/2)//first half pattern
                printf("%d",n--);
            else if(col+row>=total+1&&row<=total/2)
                printf("%d",++n);
            else
                printf("%d",n);
            printf(" ");
        }
        printf("\n");
    }
    return 0;
}
