## sametree
## **WARNING! VERY IMPORTANT!**
For this exercise a function will be tested **with the exam own main** . However the student **still needs** to submit a structured program:
This means that:
- The package needs to be named `package main` .
- The submitted code needs one declared function main(```func main()```) even if empty.
- The function main declared needs to **also pass** the `Restrictions Checker` (illegal functions tester). It is advised for the student to just empty the function main after its own testing are done.
- Every other rules are obviously the same than for a `program` .
### Instructions
Given two binary trees, write a function to check if they are the same or not.
Two binary trees are considered the same if they are structurally identical and the nodes have the same value.
Write a function, `IsSameTree` , that returns `bool` .
### Expected function
```go
type TreeNodeL struct {
Left *TreeNodeL
Val int
Right *TreeNodeL
}
func IsSameTree(p *TreeNodeL, q *TreeNodeL) bool {
}
```
Example 1:
Input:
1
/ \
2 3
[1,2,3]
1
/ \
2 3
[1,2,3]
Output: true
Input:
1
/
2
[1,2]
1
\
2
[1,null,2]
Output: false
Input:
```
1
/ \
2 1
[1,2,1]
1
/ \
1 2
[1,1,2]
```
Output: false
### Usage
Here is a possible program to test your function :
```go
package main
func main() {
t1 := NewRandTree()
t2 := NewRandTree()
fmt.Println(IsSameTree(t1, t2))
}
```
### Output
```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
true
student@ubuntu:~/[[ROOT]]/test$
```
