Today we learned how to build truth tables in order to understand our symbolic statements better. Build a truth table (that's right, the entire truth table) for the following statements: 1. ~ B ∨ X2.

In a row of seats, 1 represents a person sitting in that seat, and 0 represents that the seat is empty. There is at least one empty seat, and at least one person sitting. Alex wants to sit in the seat such that the distance between him and the closest person to him is maximized. Return that maximum distance to closest person. A. Example 1: i. Input: [1, 0, 0, 0, 1, 0, 1] ii. Output: 2 • Explanation: • If Alex sits in the second open seat (seats[2]), then the closest person has distance 2. • If Alex sits in any other open seat, the closest person has distance 1. • Thus, the maximum distance to the closest person is 2.
