Which is Italy's longest river?
Reno (river) Reno (river) The Reno () is a river of Emilia-Romagna, northern Italy. It is the tenth longest river in Italy (the sixth longest of those that flow directly into the sea) and the most important of the region apart from the Po. It has a drainage basin of about . The annual average discharge at the mouth is about ; at the point the river start to flow in the Pianura Padana (Po River Plain), it amounts to about . The highest values registered at the mouth have approached , but the typical value when the river is in flood
Longest increasing subsequence the binary Van der Corput sequence a longest increasing subsequence is This subsequence has length six; the input sequence has no seven-member increasing subsequences. The longest increasing subsequence in this example is not unique: for instance, are other increasing subsequences of equal length in the same input sequence. The longest increasing subsequence problem is closely related to the longest common subsequence problem, which has a quadratic time dynamic programming solution: the longest increasing subsequence of a sequence "S" is the longest common subsequence of "S" and "T", where "T" is the result of sorting "S". However, for the special case
