}The logic that you used is perfectly fine. It is showing wrong output because you have not taken in account the number of spaces between consecutive numbers.
For eg : the actual output for 3rd line is 1 2 3 3 2 1 , but your code will print 123 321.
Just add the spaces between consecutive numbers and your code will work for sure.
Hope that helps.
