Given a singly linked list L: L0→L1→…→Ln-1→Ln,
reorder it to: L0→Ln→L1→Ln-1→L2→Ln-2→…
You must do this in-place without altering the nodes' values.
For example,
Given {1,2,3,4}, reorder it to ...

图结构(Graph Structures)是了解Theano内在工作原理的基础。
Theano编程的核心是用符号占位符把数学关系表示出来。
图结构的组成部分
如图实现了这段代码:
importtheano.tensor as T
x= T.matrix('x')
y= T.matrix('y')
z= x + y
变量节点(variable nodes)
