Prompts the user at the command line for one $3-$character string.

Verify this first string contains $3$ characters; if not, print error and exit

program.

Then prompt the user for a $4-$character string.

Verify this second string contains $4$ characters; if not, print error and

exit program.

Print out the two input strings with one space between them.

Finally prints on a separate line the two input strings $\text{'}$in reverse' $($see

example below$)$ with a space between them.

So$,$ for example, if the first string is 'use' and the second string is 'this',

your program would output something like the following:

The two strings you entered are: use this.

The two strings in reverse are: siht esu.

Note that the reversed SECOND string comes FIRST when printing the

strings in reverse.

This program must be completed WITHOUT using loops and without using

StringBuilder.
