You are given string *s*. Your task is to determine if the given string *s* contains two non-overlapping substrings "AB" and "BA" (the substrings can go in any order).
The only line of input contains a string *s* of length between 1 and 10<sup class="upper-index">5</sup> consisting of uppercase Latin letters.
def contains_non_overlapping_AB_BA(s):
    # Check for "AB" followed by "BA"
    for i in range(len(s) - 1):
        if s[i:i + 2] == "AB" and "BA" in s[i + 2:]:
            return "YES"

    # Check for "BA" followed by "AB"
    for i in range(len(s) - 1):
        if s[i:i + 2] == "BA" and "AB" in s[i + 2:]:
            return "YES"

    return "NO"

# Example usage:
s = input().strip()
result = contains_non_overlapping_AB_BA(s)
print(result)
