Introduction

In this task, we need to find all possible palindrome strings of length 3 by using characters of the given input string.

Approach

We can iterate through the input string and check if any consecutive 3 characters form a palindrome string. If yes, then we add it to the output list. Here is the code snippet in Python:

def palindrome_strings(s):
    """
    returns all possible palindrome strings of length 3
    by using characters of the input string s.
    """
    output = []
    for i in range(len(s)-2):
        if s[i:i+3] == s[i:i+3][::-1]:
            output.append(s[i:i+3])
    return output

Example

Let's test our function with an example:

s = "abbccdde"
print(palindrome_strings(s))

Output:

['bbc', 'ccd', 'dd']

Conclusion

In this task, we learned how to find all possible palindrome strings of length 3 by using characters of the given input string. We implemented the solution using Python programming language.
