Leetcode - 100. Same Tree

Leetcode - 100. Same Tree

• Given the roots of two binary trees p and q, 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.

Solution

func isSameTree(p *TreeNode, q *TreeNode) bool {
    if p == nil && q == nil{
        return true
    }

    if p==nil || q==nil{
        return false
    }
    
    if p.Val != q.Val{
        return false
    }

    left := isSameTree(p.Left, q.Left)
    right := isSameTree(p.Right, q.Right)

    return left && right
}
