yuan, to find the smallest number of ways to make up.Analysis:Since the mother function has not been studied, the general knowledge is used to solve it.1, when there is no one-dollar coin, it must be 1.2, when a dollar coin and two yuan coins can not form all the numbers between 1-4, then do not consider the five yuan of coins, this time the smallest number is a+2*b+1.3, when the first 2 cases are satisfied, the largest number of a+2*b+5*c within all the numbers will certainly be able to take,

first and win. So what is the SG value for each number?Sg[0]=0,N=1, you can take {1} stones, remaining {0}. Mex{sg[0]}={0}. therefore sg[1]=1;When n=2, you can take {1} of stones. Remaining {1}, mex{sg[1]}={1}. therefore sg[2]=0;When n=3. Be able to take {1,3} stones, remaining {2,0} each. mex{sg[2],sg[0]}={0,0}, so sg[3]=1;N=4, you can take {1,3,4} stones. Remaining {3,1,0}, mex{sg[3],sg[1],sg[0]}={1,1,0}, so sg[4]=2;When n=5. Be able to take {1,3,4} a stone. Remaining {4,2,1}, mex{sg[4],sg[2]

Link: Best SolverTopic Analysis:The key point of this topic is the need to know "conjugate".such as:(A√b + c√d) and (a√b-c√d) are conjugatedThis has a regular (a√b + c√d) ^n + (a√b-c√d) ^n is an integer (here you can write and try it out).By the topic:Because we are asking for:(5+2√6 ) ^ (1+2 x), we can construct a pair of conjugate numbers. (5- 2 √6) ,Because 05-2√6) 5-2√6) ^n Therefore: Our formula is known by the nature of the conjugate, y = (5+2√6)^(1+ 2x) + (5-2√6) ^ (1+2 x)-1; (Y
