Any set of words is called a language. For example

$\{00,101,011\}$ and $\{$w : w in $\{0,1\}$

$$

$,|$w$|$ is even$\}$

are two languages, such that the first one is finite, and the second one is infinite and consists of all

binary words of even length.

Indicate whether each of the following languages over the alphabet $\{0,1\}$ is finite or infinite$$no

explanations required. If the language is finite, tell how many words it contains.

L$1=\{0,11\}$

$$

L$2=\{0,1\}$

$$ L$1$

L$3=\{0,1\}$

$11\backslash$cup $\{0\}$

$1040$

L$4=\{$w $|$ w contains exactly $71$s$\}$

L$5=\{$w $|$ w contains no $00\}$

L$6=\{$w $|$ w contains at most $80$s$\}\backslash$cap L$4$
