Sleep In

Background

Congcong is a programmer who loves life. Every day, he faces an important decision: should he sleep in today? This decision depends on whether it's a weekday or a weekend, and whether he is on vacation.

Problem Description

Congcong sleeps in if it is not a weekday (i.e., weekday is false) OR he is on vacation (i.e., vacation is true). Return true if Congcong sleeps in, otherwise return false.

Sample Explanation

Sample 1: weekday is false (weekend), vacation is false (not on vacation). Since it's the weekend, Congcong sleeps in, returning true. Sample 2: weekday is true (weekday), vacation is false (not on vacation). Since it's a weekday and not on vacation, Congcong does not sleep in, returning false. Sample 3: weekday is false (weekend), vacation is true (on vacation). Even though it's the weekend, he is also on vacation, so Congcong sleeps in, returning true.
