An array is considered special if every pair of its adjacent elements contains two numbers with different parity.
\n\nYou are given an array of integer nums and a 2D integer matrix queries, where for queries[i] = [fromi, toi] your task is to check that subarray nums[fromi..toi] is special or not.
Return an array of booleans answer such that answer[i] is true if nums[fromi..toi] is special.
\n
Example 1:
\n\nInput: nums = [3,4,1,2,6], queries = [[0,4]]
\n\nOutput: [false]
\n\nExplanation:
\n\nThe subarray is [3,4,1,2,6]. 2 and 6 are both even.
Example 2:
\n\nInput: nums = [4,3,1,6], queries = [[0,2],[2,3]]
\n\nOutput: [false,true]
\n\nExplanation:
\n\n[4,3,1]. 3 and 1 are both odd. So the answer to this query is false.[1,6]. There is only one pair: (1,6) and it contains numbers with different parity. So the answer to this query is true.\n
Constraints:
\n\n1 <= nums.length <= 1051 <= nums[i] <= 1051 <= queries.length <= 105queries[i].length == 20 <= queries[i][0] <= queries[i][1] <= nums.length - 1Compiled with clang 17 using the latest C++ 20 standard, and libstdc++ provided by GCC 11.
