DOubt in editorial given

#1

Hi i coded solution and only one test case was passed so i unlocked the editorial and I faced an issue understanding it that why we used a vector to store all our kth node rather than normally print it


here is the code

Hi Deep,
so we are using a vector because we have to print the nodes in ascending order… so we sort them and print them…
also if vector is empty we have to print 0 as stated in ques… so these conditions would not have been satisfied by ur code…
u can refer my code also --> https://ide.codingblocks.com/s/623307
