Use loop to print values as requested

Question

Hi question how do I print out above in console from processing.

    int result;
    for (int i=100 ; i < = 10; i + = 10) { 
       result = 100; 
       for (int k=2; k <= 10; k++) { 
          result-=10 ; 
       } print(result);
        println();
    }

• My thought is it looks like a 10*10 table thus both i and k is < = 10.
• And other thought is when i is odd i starts from 100 and -=10 (i > = 10) when i is even(line 2,4,6...) i start from 10 and +=10 ( i<=100) Then I got the printed table.

But I am stuck how to achieve this in code if my logic is correct as mentioned above.

You can do it with 2 nested loops:

for (int i=0; i<10; ++i) { 
     for (int j=0; j<10; ++j) {
        print(str(i%2 == 0 ? (10-j)*10 : (j+1)*10) + " ");
     }
     println();
}

Or one single loop:

for (int i=0; i<100; ++i) { 
     int j = i%10;
     print(str((i/10)%2 == 0 ? (10-j)*10 : (j+1)*10) + " ");
     if (i % 10 == 9) {
       println();
     }
}

Output:

100 90 80 70 60 50 40 30 20 10 
10 20 30 40 50 60 70 80 90 100 
100 90 80 70 60 50 40 30 20 10 
10 20 30 40 50 60 70 80 90 100 
100 90 80 70 60 50 40 30 20 10 
10 20 30 40 50 60 70 80 90 100 
100 90 80 70 60 50 40 30 20 10 
10 20 30 40 50 60 70 80 90 100 
100 90 80 70 60 50 40 30 20 10 
10 20 30 40 50 60 70 80 90 100
