You have k lists of sorted integers in non-decreasing order. Find the smallest range that includes at least one number from each of the k lists.

\n\n

We define the range [a, b] is smaller than range [c, d] if b - a < d - c or a < c if b - a == d - c.

Example 1:

\n\n
\nInput: nums = [[4,10,15,24,26],[0,9,12,20],[5,18,22,30]]\nOutput: [20,24]\nExplanation: \nList 1: [4, 10, 15, 24,26], 24 is in range [20,24].\nList 2: [0, 9, 12, 20], 20 is in range [20,24].\nList 3: [5, 18, 22, 30], 22 is in range [20,24].\n
\n\n

Example 2:

\n\n
\nInput: nums = [[1,2,3],[1,2,3],[1,2,3]]\nOutput: [1,1]\n
