Problem:define a recursive function to generate all Anagrams of a given stringTest Case 1:Enter a word: abcabcacbbacbcacabcbaTest Case 2:Enter a word: ababba

Sure, here is a Python solution for generating all anagrams of a given string using recursion:

def generate_anagrams(word):
    if len(word) <= 1:
        return [word]

    # Get all permutations of length N-1
    permutations = generate_anagrams(word[1:])
    char = word[0]
    result = []
    # Iterate through all permutations of length N-1
    for perm in permutations:
        # Insert the character into every possible location
        for i in range(len(perm)+1):
            result.append(perm[:i] + char + perm[i:])
    return result

You can test this function with your test cases like this:

print(generate_anagrams('abcabcacbbacbcacabcba'))
print(generate_anagrams('ababba'))

Please note that the number of anagrams for a string of length N is N factorial (N!). So, for long strings, this function may take a very long time to run and may consume a large amount of memory.
