### 方法一
### 方法一：遍历

我们从头开始遍历数组 $\textit{arr}$，对于每个元素 $\textit{arr}[i]$，我们检查 $\textit{arr}[i]$ 是否等于 $\textit{arr}[i + \left\lfloor \frac{n}{4} \right\rfloor]$，其中 $n$ 是数组的长度。如果等于，那么 $\textit{arr}[i]$ 就是我们要找的元素，直接返回即可。

时间复杂度 $O(n)$，其中 $n$ 是数组 $\textit{arr}$ 的长度。空间复杂度 $O(1)$。

### Solution 1
### Solution 1: Traversal

We traverse the array $\textit{arr}$ from the beginning. For each element $\textit{arr}[i]$, we check if $\textit{arr}[i]$ is equal to $\textit{arr}[i + \left\lfloor \frac{n}{4} \right\rfloor]$, where $n$ is the length of the array. If they are equal, then $\textit{arr}[i]$ is the element we are looking for, and we return it directly.

The time complexity is $O(n)$, where $n$ is the length of the array $\textit{arr}$. The space complexity is $O(1)$.
