    3152 - Special Array II.

    Medium

    An array is considered special if every pair of its adjacent elements contains two numbers with different parity.

    You are given an array of integer nums and a 2D integer matrix queries, where for <code>queriesi = from<sub>i</sub>, to<sub>i</sub></code> your task is to check that subarray <code>numsfrom<sub>i</sub>..to<sub>i</sub></code> is special or not.

    Return an array of booleans answer such that answer[i] is true if <code>numsfrom<sub>i</sub>..to<sub>i</sub></code> is special.

    Example 1:

    Input: nums = 3,4,1,2,6, queries = [0,4]

    Output: false

    Explanation:

    The subarray is [3,4,1,2,6]. 2 and 6 are both even.

    Example 2:

    Input: nums = 4,3,1,6, queries = [0,2,2,3]

    Output: false,true

    Explanation:

    • The subarray is [4,3,1]. 3 and 1 are both odd. So the answer to this query is false.

    • The subarray is [1,6]. There is only one pair: (1,6) and it contains numbers with different parity. So the answer to this query is true.

    Constraints:

    • <code>1 <= nums.length <= 10<sup>5</sup></code>

    • <code>1 <= numsi<= 10<sup>5</sup></code>

    • <code>1 <= queries.length <= 10<sup>5</sup></code>

    • queries[i].length == 2

    • 0 &lt;= queries[i][0] &lt;= queries[i][1] &lt;= nums.length - 1
