PROGRAMMING:Simple mathematical problems
Liu Xiaoxiao recently in preparation for postgraduate entrance examination, Liu Xiaoxiao's high number is very powerful. Today, he doesn't want to do complicated high number problems, but he has to finish one math problem every day. Why? Because life needs a sense of ceremony!!!
Now he has an array of $$n $$numbers. He needs to take two of the $$n $$numbers (which can be the same) to maximize their XOR. But he felt that he only knew the answer, not the sense of ceremony, so he wanted to know the smallest subscript of the two numbers
###Input format:
The first line contains a number $$n $, indicating the length of the number $$(1 < = n < = 5e5)$$
The second line contains the number of $$n $$$a_ I $$represents the array $$(1 < = a)_ i<=1e9)$$
###Output format:
Output a number, which indicates the minimum subscript of the two largest XOR numbers.
###Input example:
Here is a set of inputs. For example:
```in
two
1 2
```
###Output example:
The corresponding output is given here. For example:
```out
one
```
