Longest strictly increasing Subsequence of an array using C++

This project gives the longest possible strictly increasing subsequence of an array which is input by the user using C++ programming language.

In this project, the user is asked to give the size of the array followed by the elements of the array.

This outputs the Longest strictly-increasing subsequence in the array using C++ programming language.

Note: A subsequence of an array is obtained by removing some elements(possibly zero) from an array.

Constraints

1 <= size of array <= 10^7

-10^7 <= element of array <= 10^7

Sample input:

Enter the size of the array 8

Enter the elements of the array 5 1 2 3 6 8 7 4

Sample output:

The Longest strictly-increasing subsequence is : 1 2 3 6 8

Explanation:

In the given array,one of the subsequences with longest possible length is 1 2 3 6 8.
