# Min XOR value

Given an integer array **A** of **N** integers, find the pair of integers in the array which have minimum `XOR` value. Report the minimum `XOR` value.

**Input Format:**

```
    First and only argument of input contains an integer array A
```

**Output Format:**

```
    return a single integer denoting minimum xor value
```

**Constraints:**

```
2 <= N <= 100 000  
0 <= A[i] <= 1 000 000 000
```

**For Examples :**

```
Example Input 1:
    A = [0, 2, 5, 7]
Example Output 1:
    2
Explanation:
    0 xor 2 = 2
Example Input 2:
    A = [0, 4, 7, 9]
Example Output 2:
    3
```

```java
public class Solution {
    public int findMinXor(int[] A) {
        Arrays.sort(A);
        int minXOR = Integer.MAX_VALUE;
        for (int i = 0; i < A.length - 1; i++) {
            minXOR = Math.min(minXOR, A[i] ^ A[i + 1]);
        }
        return minXOR;
    }
}
```
