Longest Bitonic Subsequence

Suppose you have an array of integers, the problem statement asks to find out the longest bitonic subsequence. The bitonic sequence of an array is considered as the sequence which first increases and then decreases. Example arr[] = {1,4,2,76,43,78,54,32,1,56,23} 7 Explanation 1 ⇒ 4 ⇒ 76 ⇒ 78 ⇒ 54 …
