* [LocalMaxima](https://www.geeksforgeeks.org/find-indices-of-all-local-maxima-and-local-minima-in-an-array/) is an algorithm to find relative bigger numbers compared to their neighbors
*
* Notes:
* - works by using divide and conquer
* - the function gets the array A with n Real numbers and returns the index of local max point (if more than one exists return the first one)
