Minimum XOR value pair
Medium Accuracy: 78.43% Submissions: 2201 Points: 4

Given an array of integers of size N find minimum xor of any 2 elements.


Example 1:

Input:
N = 3
arr[] = {9,5,3}
Output: 6
Explanation: 
There are 3 pairs -
9^5 = 12
5^3 = 6
9^3 = 10
Therefore output is 6.

Your Task:  
You don't need to read input or print anything. Your task is to complete the function minxorpair() which takes the array arr[], its size N as input parameters and returns the minimum value of xor of any 2 elements.


 

Expected Time Complexity: O(N)
Expected Auxiliary Space: O(N)


 

Constraints:
1 <= N <= 105

1 <= arr[i] <= 105
