The tasks include creating strings using defined alphabets, and performing simple string operations.

Instructions:

Creating Strings:

Using alphabet $\backslash$Sigma $1=\{0,1\},$ create three different strings, each of length $4.$

Using alphabet $\backslash$Sigma $2($the English alphabet$),$ create a word of your choice and note its length.

Basic String Operations:

For one of the strings created from $\backslash$Sigma $1,$ find and write its reverse.

Identify and list all substrings of the word created from $\backslash$Sigma $2($including the empty string$).$

Concatenation Practice:

Concatenate two of the binary strings created from $\backslash$Sigma $1$ and note the length of the resulting string.

Concatenate the empty string $\backslash$epsi with the word created from $\backslash$Sigma $2$ and observe any changes.
