Given a string s and an integer k, return true if you can use all the characters in s to construct k palindrome strings or false otherwise.
Example 1:
Input: s = "annabelle", k = 2 Output: true Explanation: You can construct two palindromes using all characters in s. Some possible constructions "anna" + "elble", "anbna" + "elle", "anellena" + "b"
Example 2:
Input: s = "leetcode", k = 3 Output: false Explanation: It is impossible to construct 3 palindromes using all the characters of s.
Example 3:
Input: s = "true", k = 4 Output: true Explanation: The only possible solution is to put each character in a separate string.
Constraints:
1 <= s.length <= 105
s consists of lowercase English letters.
1 <= k <= 105
