### 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`.

||
|
|
||
|
```go
|
||
|
package main
|
||
|
|
||
|
func main() {
|
||
5 years ago
|
t1 := NewRandTree()
|
||
|
t2 := NewRandTree()
|
||
5 years ago
|
|
||
5 years ago
|
fmt.Println(IsSameTree(t1, t2))
|
||
5 years ago
|
}
|
||
|
```
|
||
|
|
||
|
### Output
|
||
|
