There are 2 while loops running. In the second iteration, the program will stay in the inner loop as an infinite loop. As the execution time is limited in playground, it shows the message "no output.

What do you mean by "longest subsequence"? Is it the length of a number (in digits), or is it the highest value from the list? It would be great if you could give us the expected output from this code.

You mentioned, that the longest increasing subsequece should be 6. May be your definition of "longest increasing subsequence" is different from my version. This is the original list a used in the code: a=[1,2,9,4,7,3,11,8,14,6] If i print a sorted version of your list "a", it looks like this: [1, 2, 3, 4, 6, 7, 8, 9, 11, 14] So for me the longest increasing subsequence is: 1,2,3,4 or 6,7,8,9. What do you think?

By longest increasing subsequence I mean If a =[1,2,9,4,7,3,11,8,14,6] So longest increasing subsequence is [1,2,4,7,11,14] whose length is 6. there can be more than one possible list but in this case it is only one which is the longest.
