Design a schema that could handle parking slots, vehicles, users, and bookings, while ensuring constraints like slot availability, entry/exit times, and vehicle type mapping. I explained the relationships between tables (e.g., Users, Vehicles, ParkingSlots, Bookings) and discussed indexing for fast lookups and scalability.

You have been given a string ‘A’ consisting of lower case English letters. Your task is to find the length of the longest palindromic subsequence in ‘A’.

A subsequence is a sequence generated from a string after deleting some or no characters of the string without changing the order of the remaining string characters. (i.e. “ace” is a subsequence of “abcde” while “aec” is not).

A string is said to be palindrome if the reverse of the string is the same as the actual string. For example, “abba” is a palindrome, but “abbc” is not a palindrome.
