Solving Keys and Rooms in go. Please try yourself first to solve the problem and submit your implementation to LeetCode before looking into solution.

Problem Description

You can walk back and forth between rooms freely.

Example 1:

Input: [[1],[2],[3],[]]
Output: true
Explanation:  
We start in room 0, and pick up key 1.
We then go to room 1, and pick up key 2.
We then go to room 2, and pick up key 3.
We then go to room 3.  Since we were able to go to every room, we return true.

Example 2:

Input: [[1,3],[3,0,1],[2],[0]]
Output: false
Explanation: We can't enter the room with number 2.

Note:

  1. 0 <= rooms[i].length <= 1000
  • 0 <= rooms[i].length <= 1000
