Given an array arr of n integers, in a single operation, one can reduce any element of the array by 1. Find the minimum number of operations required to make the array a bitonic array.
`Example of a bitonic array: [0,1,2,3,2,1,0,0].

I’m working on a project where I need to find the longest increasing subsequence (LIS) from a given array of integers. However, the array can be quite large, so I’m looking for an efficient algorithm to solve this problem.
