Hello Programmers In this post, you will know how to solve the AND Plus OR Codechef Solution. The Problem Code: ANDOR

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

### Problem

Given an integer x, find two non-negative integers a and b such that (a∧b)+(a∨b)=x(a∧b)+(a∨b)=x, where ∧ is the bitwise AND operation and ∨ is the bitwise OR operation.

### Input

• The first line of the input contains a single integer T denoting the number of test cases. The description of T test cases follows.
• The first and only line of each test case contains a single integer x.

### Output

If there is no valid pair (a,b), print a single line containing the integer −1. Otherwise, print a single line containing two space-separated integers aa and bb.

If there are multiple solutions, you may print any one of them.

### Constraints

• 1≤T≤1051≤T≤105
• 1≤x≤10181≤x≤1018

Subtask #1 (30 points):

• 1≤T≤2001≤T≤200
• 1≤x≤2001≤x≤200

Subtask #2 (70 points): original constraints

### Sample Input 1

``````2

### Sample Output 1

``````0 1
5 3
``````

### AND Plus OR CodeChef Solution in JAVA

```import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int T = sc.nextInt();
for (int tc = 0; tc < T; ++tc) {
long x = sc.nextLong();
System.out.println(solve(x));
}
sc.close();
}
static String solve(long x) {
return String.format("0 %d", x);
}
}```
