Best case:
When even numbers of 1/3 are all 0.2xxx, the profit when carrying is 0.8.
However, the remaining 2/3 elements with a decimal of 0. 1xxx will lose 0. 1 when they abdicate.
The difference of E-S is 0.8* 10-0. 1*20=6.
Worst case:
When the even numbers of 1/3 are all 0.8xxx, the profit when carrying is 0.2.
The remaining 2/3 element decimal is 0.9xxx, which means that 0.9 is lost when abdicating.
The difference of E-S is 0.2 *10-0.9 * 20 =-16.
