<b><font face="Arial, Helvetica, sans-serif" size="4" color="#000000">〖<font color="#FF0000">example</font>〗
 operation sequence:<i><font color="#0033CC"> I1, I2, D1, I3, I4, I5, I6, D2, I7</font></i>
  actual cost:  <i> I1 ~ I7   -- 1,   D1 - 8,    D2 --  10</i> ( unit of  time )
  total cost = 25
  if  2 units <i>(D1) -->  I1, I2, </i>    4 units <i>( D2) --> I2 ~ I6</i>

the amortized cost  of each of <i>I1 ~ I6</i>  =  2 units
the amortized cost  of each of <i>D1 ~  C2</i> =  6 units
the total amortized cost   =  (2*6+1*+2*6 ) = 25 units

for any sequence of insert and delete min operations:
 	<font color="#0033CC">actual sequence cost  </font>=  i + 10 * d
	<font color="#0033CC">amortized sequence cost</font> =  2 * i + 6 * d
bound on  the sequence cost = min {2 * i + 6 * d, i + 10 * d}

while individual delete operations on an binomial heap may be
 expensive, the cost of any sequence of binomial heap operations
 is actually quite small
