Change it to read-only access
I'll complete that sentence: Change it to read-only access or you'll end up like Mountain Dew during their Dub the Dew campaign.
in ArraySorting we have to find longest non-decreasing Sequence instead LIS and change other elements.right?
Yes.
Can anybody please explain the solution to the problem "Array Sorting". As i am not good with dp, i am not able to understand the editorialist's approach.
Do you know how to find Longest Increasing Subsequence?
Yes, i know that much.
The answer is n — size of LIS.
Does that mean i just have to set the values of the other elements which are not in the LIS to the minimum possible?
Yes.
