◆ONE HUNDRED COINS
In how many ways 100 gold coins can be divided into groups, so that the
difference between any two groups is at most 2?
Note: Permutations are not considered as different.
Example: If the problem was asked for 6 coins, the answer would be 9:
(1,1,1,1,1,1), (1,1,1,1,2), (1,1,2,2), (1,1,1,3), (1,2,3), (2,2,2), (2,4),
(3,3), (6).
現要把一百枚金幣分成數堆，使得任意兩堆的金幣數都最多差２，有幾種方法？
# 重新排列並不視為不同的方法
舉例: 6個金幣有9種分法:
(1,1,1,1,1,1), (1,1,1,1,2), (1,1,2,2), (1,1,1,3), (1,2,3), (2,2,2), (2,4),
(3,3), (6).
