hey was jus wondering if anyone knew how to create the following sequences as below:

1)

54321
 4321
  321
   21
    1

2)

123
321

and also how to reverse an int.

Thank You,
Cheers,

what u need is the data structure algorithm, image u store each element into a single room, then rotate the room to left, just like left shift it. Ex: room[0] = 1, room[1] = 2, room[2] = 3, then output it as room[2]room[1]room[0] = 321.
There may be better solutions, i just suggest one of it.

for(int i=1; i<6; i++){
    for(int j=6-i; j>0; j--)
        printf("%d", j);
    printf("\n");
}

Best Regards,
