Master SQL Interview Questions: Detailed Solution to LeetCode 175 for Top Tech Companies 🚀

In this video I solve and explain a leetcode SQL question using MySQL query. This question has been asked in Apple, Facebook, Amazon, Google, Adobe, Microsoft, Adobe interviews or what we popularly call FAANG interviews.

SQL Schema:
Create table If Not Exists Person (personId int, firstName varchar(255), lastName varchar(255))
Create table If Not Exists Address (addressId int, personId int, city varchar(255), state varchar(255))
Truncate table Person
insert into Person (personId, lastName, firstName) values ('1', 'Wang', 'Allen')
insert into Person (personId, lastName, firstName) values ('2', 'Alice', 'Bob')
Truncate table Address
insert into Address (addressId, personId, city, state) values ('1', '2', 'New York City', 'New York')
insert into Address (addressId, personId, city, state) values ('2', '3', 'Leetcode', 'California')

I explain the related concept as well. This question is about combining two tables and also includes points to keep in mind to develop SQL queries.
