前几天复习了一下对分查找(Binary Search),它提供了在O(log N)时间内的 Find (查找操作),先来看看对分查找的叙述要求: 给定一个整数 X 和整数 ,后者已经预先排序,并且已经在内存中,求使得 的下标 i ,如果 X 不在数据之中,则返回 i = -1。 来看看实现源码: 1 2 3 4 5 6 7 8 9 10 11 12 1...

Part C— Basic binary search situations Task C1 You've got nn trees, the ii-th tree has the height of hihi meters. You are going to cut them. You are going to determine a value xx, which is the height of the saw. And then: For trees with hi≥xhi≥x, do hi←xhi←x, and ...
