/*
* this is algo which implies common mathematical set theory concept
* called intersection in which result is common values of both the sets
* here metaphor of sets is HashMap
Test Case:
Scanner scn=new Scanner(System.in);
int len =scn.nextInt();
int arr[]=new int[len];
int arr2[]=new int[len];
for(int i=0;i<2*len;i++) {
if(i<len)
arr[i]=scn.nextInt();
if(i>=len) {
arr2[i-len]=scn.nextInt();
}
}
System.out.println(Main(arr,arr2));
