Given an array of integer arrays arrays where each arrays[i] is sorted in strictly increasing order,
return an integer array representing the longest common subsequence among all the arrays.
A subsequence is a sequence that can be derived from another sequence by deleting some elements (possibly none)
without changing the order of the remaining elements.
Example 1:
Input: arrays = [[1,3,4],
[1,4,7,9]]
Output: [1,4]
Explanation: The longest common subsequence in the two arrays is [1,4].
Example 2:
Input: arrays = [[2,3,6,8],
[1,2,3,5,6,7,10],
[2,3,4,6,9]]
Output: [2,3,6]
Explanation: The longest common subsequence in all three arrays is [2,3,6].
Example 3:
Input: arrays = [[1,2,3,4,5],
[6,7,8]]
Output: []
Explanation: There is no common subsequence between the two arrays.
Constraints:
2 <= arrays.length <= 100
1 <= arrays[i].length <= 100
1 <= arrays[i][j] <= 100
arrays[i] is sorted in strictly increasing order.
