You have k
lists of sorted integers in ascending order. Find the smallest
range that includes at least one number from each of the k
lists.
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:
Input: [[4,10,15,24,26], [0,9,12,20], [5,18,22,30]] Output: [20,24] Explanation: List 1: [4, 10, 15, 24,26], 24 is in range [20,24]. List 2: [0, 9, 12, 20], 20 is in range [20,24]. List 3: [5, 18, 22, 30], 22 is in range [20,24].
