# Return Strings That Do Not Contain Identical Neighbors

# Consider all words of length N, consisting only of letters "b' and/or "c",
# that do not contain two identical neighbouring letters.
# For example, "aba' is such a word but "abb" is not (two letters "b" occur
# next to each other).
# We are interested in finding the K alphabetically smallest words of length
# N that do not contain two identical neighbouring letters.
# For example, the first four words consisting of two letters are: "ab',
# "ac•, "ba", "bc•.
# All correct two-letters words are: "ab", "ac", "ba•, "bc", "ca•, "cb".

# Find and fix bug(s) in a given implementation of a function:

# class Solution { public String[] solution(int N, int K) }

# that, given integers N and K, retums an array of strings: the first
# K words of the alphabetically sorted sequence of words of length
# N, in which no two neighbouring letters are the same. If K is
# bigger than the sequence's length, the entire sequence is returned.

# Examples:
# 1 . Given N = 2 and K = 4, the function should retum tab", "ac", "ban,
# 'bc'] as explained above.
# 2. Given N = 3 and K = 20, the function should retum ['aba", •abc",
# •aca", •acb", "bab", "bac", 'bca", "bcb', "cab", •cac•, "cba",
# "cbcl.
# 3. Given N = 5 and K = 6, the function should retum ['ababa", "ababc•,
# "abaca', "abacb", "abcab", •abcac"].

# The attached code is still incorrect for some inputs.
# Despite the error(s), the code may produce a correct answer for the
# example test cases.
# The goal of the exercise is to find and fix the bug(s) in the
# implementation.
# You can modify at most two lines.

# Assume that:
# N is an integer within the range [1..101;
# K is an integer within the range [1..100].

# In your solution, focus on correctness.
