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
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
