#1


I should get output as 2 1 3 but getting 2 3 1.
Please resolve .
also resolve TLE.

#2

Try printing elements corresponding wise as provided in the input.
You are sorting the vector which is causing the issue

#3

can you please elaborate?

#4

While printing the values from the hash, take prints in the same order as the input. Do not sort the values unless necessary.
Also it is good idea to use a hashmap in this situation rather than a vector since it provides a key value correspondence, thus each input value’s hash can be retrieved from the map in O(1) time
