you have to find the kth element of your list. which will take O(n) and remaining element you can get in the other traversal eg: 3,5,4,35,599,34 you have to find the 3 min element from the lsit so finding 3rd element we will get 5 on next thing is traverse the list and take all the element less than 5, eg:3,5,4 is this clear your doubt ...? or i have gone on the other way...
