int main() {
    int n,k;
    scanf("%d",&n);
    for(int i=0; i<n; i++){
        k = n;
        for(int j=0; j<2*n-1; j++) {
            printf("%d ",k);
            k = (((k-j)>(k-i)) && (j < 2*(n-1)-i)) ? k-1 : k;
            k = ((k < n) && (j >= 2*(n-1)-i)) ? k+1 : k;
        }
        printf("\n");
    }
    for(int i=n-2; i>-1; i--){
        k = n;
        for(int j=0; j<2*n-1; j++) {
            printf("%d ",k);
            k = (((k-j)>(k-i)) && (j < 2*(n-1)-i)) ? k-1 : k;
            k = ((k < n) && (j >= 2*(n-1)-i)) ? k+1 : k;
        }
				
				This code mimics signal processing and stuff used in Digital Systems, Ive used concept of DEMUX and split the loop conditions 

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

    }
