ArrayListWrite a method longestSorted that takes an ArrayList of integers as parameter and returns the length of the longest sorted sequence within this list.lor example, it a varable $118$ se stores these values:$[1,3,5,2,8,6,-3,1,42,63,17]$Then the call longestSorted $($list$)$ would return $1$ because it is the length of the longest sorted sequence $($which is $-3,1,42,63)$ within the list.If your ArrayList is empty, the method should return $0.$Notice that for a non$-$empty list the method will always return a value of at least I because any individual integer constitutes a sorted sequence.
