"Inferior currency expulsion of good currency" is a famous law in economics. The law is a generalization of a historical phenomenon: in the age of coinage, when those less than the legal weight or the color of the coinage-"bad money" into circulation, people tend to the full value of the currency-"good currency" collection. Finally, the good currency will be expelled, the market is only a bad currency in circulation. The information asymmetry of the parties is the basis of the phenomenon of "inf

Question: place n coins in a circle, numbered 1-n. You can only flip 1-n coins in a row ~ K coins. The winner of the last coin wins.
Idea: Game
1) if k = 1, you can only flip one at a time. an odd number of first-hand wins and an even number of second-hand wins.
2) if k> 1:A: The first hand is used up once to win the first hand;B: The first hand cannot be finished, and the ring must be broken for the first time. As long as the latter hand completes on

Description
There are n kinds of coins. the nominal value is a [1], a [2], a [3]… A [n], each of which has an infinite number. Given a non-negative integer S, how many coins can be selected to make the nominal value and exactly s? Output the minimum and maximum number of coins
Generally, the primary function uses the power series to represent a discrete series. For example, if a series is a = {A0, A1, A2, ------- AK}, then the definition of the primary function is g (x) = A0 + A1 * x + A2 * x ^ 2 + A3 * x ^ 3 ------ An * x ^ n, where G (x) is the primary function of Series.
The primary function can be used to solve the integer splitting problem. The following is an example.
For example, if we have one weight for one gram, two grams, three grams, and four grams, how ma

Five coins for you:, 50. Now we give you an n to find the number of types that contain the value n, for example, n = 11;
1. 11 items 1
2. 1 10, 1 1
3, 1, 5, 6, 1
4, 2 5, 1 1
Note: The number of coins used cannot exceed 100. You only need to pay attention to this.

There are coins with different nominal values in n. the nominal values of each coin exist in the array T [1. N]. The number of nominal coins that can be used is not limited. Assume that the current sum of money is J, 1
Solution:
The other C [I, j] represents the minimum number of coins used to redeem J.
