```python
def can_break(s1, s2):
    sorted_s1, sorted_s2 = ''.join(sorted(s1)), ''.join(sorted(s2))
    
    def check_break(x, y):
        return all(x[i] >= y[i] for i in range(len(x)))

    return check_break(sorted_s1, sorted_s2) or check_break(sorted_s2, sorted_s1)

# Example usage:
s1 = "abc"
s2 = "xya"
print(can_break(s1, s2))  # Output: True

s1 = "abe"
s2 = "acd"
print(can_break(s1, s2))  # Output: False

s1 = "leetcodee"
s2 = "interview"
print(can_break(s1, s2))  # Output: True
