Solve the following python programming problem given the following code:
@ classmethod 
def _is_connected(cls, x, y) : 
    '
        Check if x and y are connected somehow.
        ' 
    from sympy.core.exprtools import factor_terms 
    def hit(v, t, f) : 
        if (not v.is_Relational) : 
            return (t if v else f) 
for i in range (2) : 
        if (x == y) : 
            return True 
r = hit ((x >= y), Max, Min) 
        if (r is not None) : 
            return r 
r = hit ((x <= x), Max, Min) 
        if (r is not None) : 
            return r 
r = hit ((x <= y), Min, Max) 
        if (r is not None) : 
            return r 
r = hit ((y >= x), Min, Max) 
        if (r is not None) : 
            return r 
x = factor_terms ((x - y)) 
        y = S.Zero 
return False 

    
    

    Fix the buggy line: r = hit ((x <= x), Max, Min)
assistant
#Here is Python program to fix the buggy line: r = hit ((x <= x), Max, Min)
.

r = hit ((y <= x), Max, Min)
