To construct k palindromes from the string s, we need:
1. At least k characters in the string. If s.size() < k, it is impossible, so return false.
2. Each palindrome can have at most one character with an odd frequency. Therefore, the total number of characters with odd frequencies in s must not exceed k.

We aim to split the `string` `s` into exactly `k` palindromic substrings.
- Palindromes need `at most 1 odd-frequency` character 🔑.
- Count odd-frequency characters . If there are more odd characters than `k`, it’s impossible to form `k` palindromes.
