Print All Longest Increasing Subsequences

easy

1. You are given a number N representing number of elements. 2. You are given N space separated numbers (ELE : elements). 3. Your task is to find & print 3.1) Length of "Longest Increasing Subsequence"(LIS). 3.2) All "Longest Increasing Subsequence(s)"(LIS). NOTE: Checkout sample question/solution video inorder to have more insight.

Constraints

1 <= N <= 100 1 <= ELE <= 1000

Format

Input

A number N (representing "NUMBER OF ELEMENTS"). ELE1 ,ELE2 ,ELE3 ,ELE4 .... ELEn (N space separated numbers represnting numbers).

Output

1) A number representing Length of "Longest Increasing Subsequence"(LIS). 2) Strings representing "Longest Increasing Subsequence(s)"(LIS). Check the sample ouput and question video.

Example

Sample Input

10 10 22 9 33 21 50 41 60 80 1

Sample Output

6 10 -> 22 -> 33 -> 41 -> 60 -> 80 10 -> 22 -> 33 -> 50 -> 60 -> 80
