a[i];=a=a[i div 2]
a[n div 2]就是答案。。。。。。。。。。。。。。。。
只不过。。。压位高精度。。。。。。。。。。 -

汗...
我还在专门找这个数列的表达式...完全当奥数题在做..确实有难度..可以当2试的了吧.
去问数学老师都没解决... -

本题若干解法按低级到高级排列:
1.直叙式递归...就是用递归生成所有解;
2.改递归为递推:F[N]=F[1]+F[2]+F[3]....+F[N div 2];O(N^2);
3.改进递推方程:F[N]=F[N-1](N为奇数)F[N]=F[N-1]+F[N div 2](N为偶数);O(N)
4.高精度、预处理....压位高精度....
5.仍然TLE和MLE.....检查RP.......茫然........
6.既然奇数位和偶数位答案是一样的,干嘛要计算和保存奇数位的答案呢?这样就省下了一半的时间和空间............
