HS(Handsome)的Ocean在纸上写下NN个整数,Ocean把它定义为OO序列. Ocean认为一个序列的价值的是:序列中不同元素个数. 现在他想知道OO序列中所有子序列的价值之和. 比如说:序列(1,1,2,2)(1,1,2,2)价值为22,因为序列中有11和22两个不同元素. 比如序列(1,1,1)(1,1,1),共有77个子序列,(1).(1).(1).(1,1).(1,1).(1,1).(1,1,1).(1).(1).(1).(1,1).(1,1).(1,1).(1,1,1).价…

The set [1,2,3,-,n] contains a total of n! unique permutations. By listing and labeling all of the permutations in order,We get the following sequence (ie, for n = 3): "123" "132" "213" "231" "312" "3…

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 se…
