JuniorArray
Special Array I
An array is considered special if the parity of every pair of adjacent elements is different. In other words, one element in each pair must be even, and the other must be odd.
You are given an array of integers nums. Return true if nums is a special array, otherwise, return false.
Example 1
Input
nums = [1]Output
trueThere is only one element, so the answer is
true.Example 2
Input
nums = [2,1,4]Output
trueThe two adjacent pairs,
(2, 1) and (1, 4), both contain numbers with different parity.Constraints
- 1 <= nums.length <= 100
- 1 <= nums[i] <= 100
