You are sorting a permutation, so all you have to do is print out the integers from $$$1$$$ to $$$n$$$, inclusive. The time constraints are very lax for this. Though you should be careful of the memory limit. If you read the second line entirely, you will probably get MLE. If you form a large string and then print it out, you will probably get MLE.
