将斐波那契数列前10项-搜答案-智慧作业帮

#includevoidmain(){inti,count=0,num[30]={1,1};for(i=2;i

为用了很没有效率的递归,所以出结果有点慢#includeiostream.h

PrivateFunctionF(nAsLong)AsLongIfn>2ThenF=F(n-1)+F(n-2)ElseF=1EndIfEndFunctionPrivateSubCommand1_Cli

现成的

通项公式为A（n-1）+An=A(n+1)11235813213455＝143

斐波那契数列前13项为1,1,2,3,5,8,13,21,34,55,89,144,2331+1+2+3+5+8+13+21+34+55+89+144+233=609

1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597,2584,4181,6765,10946,17711,28657,46368,75025,121

(1/√5)*{[(1+√5)/2]^n-[(1-√5)/2]^n这个是斐波那契数列的通项公式,差分方程的z变换可求得要算前n项和就很简单了吧
