WebMar 2, 2024 · The given array is already a bitonic array. Therefore, the required output is 3. Recommended: Please try your approach on first, before moving on to the solution. Approach: The problem can be solved based on the concept of the longest increasing subsequence problem. Follow the steps below to solve the problem: WebAug 13, 2024 · Given an array arr[N] of N integers, the task is to check whether the given array is bitonic or not. If the given array is bitonic then print “Yes its a bitonic array”, else print “No its not a bitonic array”. A Bitonic array is when the array is in strictly increasing order first and then in strictly decreasing order.
