 ## Description
+An array is considered **special** if every pair of its adjacent elements contains two numbers with different parity.
+
+You are given an array of integers `nums`. Return `true` if `nums` is a **special** array, otherwise, return `false`.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: nums = [1]
+
+Output: true
+
+Explanation:
+
+There is only one element. So the answer is true.
+```
+
+**Example 2:**
+
 ```
+Input: nums = [2,1,4]
+
+Output: true

-Special Array I
-```go
 ```
+Input: nums = [4,3,1,6]
 
+Output: false
+
+Explanation:
+
+nums[1] and nums[2] are both odd. So the answer is false.
