Given an integer array `queries` and a positive integer `intLength`, return an array `answer` where `answer[i]` is either the `queries[i]th` smallest positive palindrome of length `intLength` or `-1` if no such palindrome exists.

A palindrome is a number that reads the same backwards and forwards. Palindromes cannot have leading zeros.

Example 1:

    Input: queries = [1,2,3,4,5,90], intLength = 3
    Output: [101,111,121,131,141,999]
    Explanation:
    The first few palindromes of length 3 are:
    101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 201, ...
    The 90th palindrome of length 3 is 999.

Example 2:

    Input: queries = [2,4,6], intLength = 4
    Output: [1111,1331,1551]
    Explanation:
    The first six palindromes of length 4 are:
    1001, 1111, 1221, 1331, 1441, and 1551.

Constraints:

- `1 <= queries.length <= 5 * 104`
- `1 <= queries[i] <= 109`
- `1 <= intLength <= 15`
