我要在 Golang 中比较二叉树。但我的答案是错误的。需要第三只眼的帮助。谢谢。
package main
import(
"fmt"
)
type TreeNode struct {
val int
left *TreeNode
right *TreeNode
}
func isSameTree(p *TreeNode , q *TreeNode ) (bool){
if p == nil && q == nil {
return true
}
if p != nil && q == nil{
return false;
}
if p ==nil && q != nil {
return false;
}
if (p.val == q.val) && (isSameTree(p.left,q.left)) && (isSameTree(p.right ,q.left)){
return true;
} else {
return false;
}
}
func main(){
p := &TreeNode{val: 1}
p.left = &TreeNode{val: 2}
p.right = &TreeNode{val: 3}
q := &TreeNode{val: 1}
q.left = &TreeNode{val: 2}
q.right = &TreeNode{val: 3}
isSame := isSameTree(p,q)
fmt.Println("is same?: ", isSame)
}
