first = input("Please input your first name: ")
last = input("Please input your last name: ")
print(last+", "+first)
I hope this helps!
Answer:
An Oracle sequence uses the identity column property to automatically number rows.
Explanation:
An Oracle sequence is a tool that can be used to generate a number sequence. Oracle has the capacity to help you create an auto-number field by using one of its tools called sequence.
A sequence is an object in Oracle that is used to generate a number sequence for input to a table. This is required when you need to generate primary key values by the use of identity columns.
So, Oracle sequence can automatically number rows by the use of identity columns.
Answer:
False
Explanation:
Kleene star is a unary operation, we can perform this on a character or set of strings.It means zero or more than zero up to infinite.
It is represented by Vˣ or V+.
For 1, the kleene star will be empty string '∈' or any number of strings.
1ˣ =(∈,1,11,111,1111,11111......)
In question, the empty string '∈' is not present.
Answer:
001*|1*00
Explanation:
The language consists of strings in {0,1} that either start with 00 or end with 00 and have no more zeros.
The requirement can be divided into two parts:
1) Strings that start with 00 and have no more zeros
2) Strings that end with 00 and have no more zeros
Generating regular expressions for these parts:
1) 001* - starts with two zeros and can have zero or more 1s later
2)1*00 - starts with zero or more 1s and ends with two zeros
So on combining with the or operator(|), the overall regular expression for the strings in the language becomes:
001*|1*00
Answer:
Magnetism
