This problem was asked in online round to my friend.I am not able to get how to approach the problem using which technique, if someone could help me?, Thanks.↵

Problem:↵
==================↵
****Alice has decided to publishto publish X different comic books.****↵
****For this Purpose , He has Y printing machines and Z binding machines.****↵
****The ith printing machine takes print[i] minutes to print all pages of a comic book. Each binding machine takes K minutes to bind all the pages of a comic book.**↵
****At a single point of time ,each machine(a printing or a binding) can process at most the pages of a single comic book.**↵
****For publishing comic books , these steps have to be followed.**↵
****1. An unoccupied printing machine i starts printing the pages of a comic book.**↵
****2. After print[i] minutes , the printed pages are taken out of the ith printing machine.**↵
****3. After non-negative amount of time , the printed pages of comic book are placed in an unoccupied binding machine.**↵
****4. After K minutes, the pages are taken out of the binding machine.**↵
↵
****Assume that the time is negligible for placing the pages into or removing from the machines.**↵
****You need to help alice , find out the minimum time in order to publish X comics.**↵
↵
Input:↵
------------------↵
1.first line consists of the no of testcases.↵
2.Second line consists of X,Y,Z,K.↵
3.Y space separted integers which denote the printing time print[i] of ith printing machine.↵
↵
### OUTPUT:↵
For each test case , print the minimum time to publish all X comics.↵
Constraints:↵
1<=t<=10↵
1<=X<=10^6↵
1<=Y<=10^5↵
1<=Z<=10^9↵
1<=K<=10^9↵
1<=print[i]<=10^9↵
