Question

Describe the language generated by each of the following RegEx: R1=(0∪10∪110)
∗R2=(0∪1) ∗ 0 +

Answer 1

The regular expression R1=(0∪10∪110) ∗ matches strings that are composed of 0, 10, or 110. The regular expression R2=(0∪1) ∗ 0 + matches strings that start with one or more 0s or 1s, followed by one or more 0s. The language generated by R1 R2 represents all possible combinations of strings generated by R1 and R2.

Step-by-step explanation:

The regular expression R1=(0∪10∪110) ∗ matches all strings that are composed of either:

1. A single 0,
2. The string 10,
3. The string 110.

The regular expression R2=(0∪1) ∗ 0 + matches all strings that start with one or more 0s or 1s, followed by one or more 0s.

The language generated by R1 R2 represents all strings that can be obtained by concatenating a string from the language generated by R1 with a string from the language generated by R2.
