不知道起什么名字

public boolean isSymmetric(TreeNode root) { if(null == root){ return true; } return isMirror(root.left, root.right);}private boolean isMirror(TreeNode r1, TreeNode r2){ //判断传入的两个节点是否属于镜像关系 //如果两个节点都为null，结束递归调用 if...

代码实现如下：import torchimport torch.nn.functional as FA = torch.ones(3,2)B = torch.ones(2,2)a = torch.Tensor([1,2,3]).reshape(3,1)b = torch.Tensor([4,5]).reshape(2,1)A = torch.mul(A,a)B = torch.mul(B,b)W = torch.rand(6,1)print('W:',W)print(A)pr..
