Longest Palindrome Length
Also known as: Longest Palindrome
Find the length of the longest palindrome that can be built Example: "abccccdd" => 7 (can build "dccaccd")
Longest Palindrome Length looks straightforward, but it quietly checks whether you reach for the right lookup structure. It's a great warm-up that builds data-structure instincts without a ton of moving parts. The signal here is clean bookkeeping: know what you record and when you update it.
