 ## Description
+A tree is an undirected graph in which any two vertices are connected by exactly one path. In other words, any connected graph without simple cycles is a tree.
+
+Given a tree of `n` nodes labelled from `0` to `n - 1`, and an array of `n - 1` `edges` where `edges[i] = [ai, bi]` indicates that there is an undirected edge between the two nodes `ai` and `bi` in the tree, you can choose any node of the tree as the root. When you select a node `x` as the root, the result tree has height `h`. Among all possible rooted trees, those with minimum height (i.e. `min(h)`)  are called **minimum height trees** (MHTs).
+
+Return a list of all **MHTs'** root labels. You can return the answer in **any order**.
+
+The **height** of a rooted tree is the number of edges on the longest downward path between the root and a leaf.

+**Example 1:**  
+
+![1](./e1.jpeg)
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: n = 4, edges = [[1,0],[1,2],[1,3]]
+Output: [1]
+Explanation: As shown, the height of the tree is 1 when the root is the node with label 1 which is the only MHT.
