How many different data types are there in SAS? What are they? Give me a brief description of each one.
There are three different data types in SAS: Fixed Length Character, Varying Length Character and Numeric. Fixed Length Character is exactly what it says in the name! It stores a fixed- length character string where n is the maximum number of bytes that can be stored. Varying Length Character is exactly what it sounds like as well, where it stores a varying length character string. N is the same in this character as well- the maximum number of characters to store. Numeric data types are a little different, in terms of that they store a numeric value rather than a string. The number value can be a time, data, etc. These number values are all stored as floating- point numbers.

Subject: Artificial Intelligence
What's the difference between strong AI and weak AI?
With strong AI systems, a machine has the ability to process and implement a single or sequence of commands self sufficiently, similar to that how a human would. For example, if a strong AI system were to hear someone say "help!", it would start dialing the number of the local emergency services on its own. On the other hand, weak AI machines are unable to do these types of tasks on their own and depend greatly on the support of humans to help cognize through the process.
