Suppose there are ‘n’ trees (literal trees, not trees of computer science, suppose they don’t have any branch, more like a straight stick), each of them have some height. We want x length of wood. We have a woodcutter, which we will use to cut all the trees at the same height ‘h’ from ground, if ‘h’ is greater than the height of any tree, means that tree is not cut. Given the heights of all the trees and length ‘x’ of wood required, output the height ‘h’ from ground from where you will cut all the trees
