Check whether the original sequence org
can be uniquely reconstructed from the
sequences in seqs
. The org
sequence is a permutation of the
integers from 1 to n, with 1 ≤ n ≤ 104. Reconstruction means building a
shortest common supersequence of the sequences in seqs
(i.e., a shortest
sequence so that all sequences in seqs
are subsequences of it). Determine
whether there is only one sequence that can be reconstructed from seqs
and it
is the org
sequence.
Example 1:
Input: org: [1,2,3], seqs: [[1,2],[1,3]] Output: false Explanation: [1,2,3] is not the only one sequence that can be reconstructed, because [1,3,2] is also a valid sequence that can be reconstructed.
Example 2:
Input: org: [1,2,3], seqs: [[1,2]] Output: false Explanation: The reconstructed sequence can only be [1,2].
Example 3:
Input: org: [1,2,3], seqs: [[1,2],[1,3],[2,3]] Output: true Explanation: The sequences [1,2], [1,3], and [2,3] can uniquely reconstruct the original sequence [1,2,3].
Example 4:
Input: org: [4,1,5,2,6,3], seqs: [[5,2,6,3],[4,1,5,2]] Output: true
UPDATE (2017/1/8):
The seqs parameter had been changed to a list of list of strings (instead of a 2d
array of strings). Please reload the code definition to get the latest changes.
