$3$ ASCII Neighbors $(50$ points$)$

Write a program that reads from standard input a sequence of whitespace$-$separated 'words'. The program should output each word on its own line, but only including the characters that

are equal or adjacent in the ASCII table. For example, the character $\text{'}i\text{'}$ has an ASCII value of $105,$ and it should be included in the output only if it is next to an $h(104),$ an i $(105),$ or a j

$(106).$ In your solution, you must use a void function named FilterNeighbors, that takes in

a string, and filters it based on the problem specification.

Example Input:

ahidkkrtsraaav

Expected Output:

hikktsraaa

The first $\text{'}a\text{'}$ isn't in the output because its only neighbor $(h)$ is not adjacent to it in the ASCII

table. The $\text{'}h\text{'}$ and the $\text{'}i\text{'}$ are adjacent in the table so they are outputted. The $\text{'}$k$\text{'}$s are equal to

each other, so they are also outputted. And so on$.$

Example Input:

$23321$ gbsyfbjlbsadfoebw $./-$$$$!$&$\%$aAJ

$\{|\}$:$($:::$)=k?$

Expected Output:

$23321$

$.\frac{?}{?}$$$$2\%$

$\{|\}$

$($The blank line in the Expected Output is the correct output for the second string of letters. Since no letters that border each other are the same nor the predecessor and successor, there is no group of letters that can be outputted, hence why it is blank.$)$

Remember that there are lots of characters in ASCII beyond just letters. The "gbsyfbjlbsad$-$foebw" word contains to letters that are adjacent in the word and in the table, so its line is empty.

When writing your program, you may only use concepts you have learned in the course as far. Your program should compile and run.

The formatting must match exactly as shown in the example above, including whitespaces.

This is a C$++$ programming language assignment Thank you
