elif max_deg == 1:
coefficients = coefficients[:2] # [b0, b1]
else:
coefficients = coefficients[:1] # [b0]
# Now, check trailing zeros for higher degrees
# For example, if max_deg is 1 but b1 is zero due to previous steps
# But since max_deg is determined by checking non-zero, this should be handled
# Now handle the case where all are zero (but earlier handled by b0=0 -> coefficients [0])
# Now, output
