## Java BitSet Hacker Rank Solution

### Problem

Java’s BitSet class implements a vector of bit values (i.e.:  () or  ()) that grows as needed, allowing us to easily manipulate bits while optimizing space (when compared to other collections). Any element having a bit value of  is called a set bit.

Given  BitSets,  and , of size  where all bits in both BitSets are initialized to , perform a series of  operations. After each operation, print the number of set bits in the respective BitSets as two space-separated integers on a new line.

### Java BitSet Hacker Rank Solution

```import java.util.*;
class Solution {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int m = sc.nextInt();
BitSet[] bits = {new BitSet(n), new BitSet(n)};
for (int i = 0; i < m; i++) {
String operation = sc.next();
int x = sc.nextInt();
int y = sc.nextInt();
switch (operation) {
case "AND":
bits[x - 1].and(bits[y - 1]);
break;
case "OR":
bits[x - 1].or(bits[y - 1]);
break;
case "XOR":
bits[x - 1].xor(bits[y - 1]);
break;
case "FLIP":
bits[x - 1].flip(y);
break;
case "SET":
bits[x - 1].set(y);
break;
default:
break;
}
System.out.println(bits[0].cardinality() + " " + bits[1].cardinality());
}
}
}```
