You are given K eggs, and you have access to a building with N floors from 1 to N.  Each egg is identical in function, and if an egg breaks, you cannot drop it again. You know that there exists a floor F with 0 <= F <= N such that any egg dropped at…

题目链接:https://leetcode.com/problems/super-egg-drop/ 题意:给你K个鸡蛋以及一栋N层楼的建筑,已知存在某一个楼层F(0<=F<=N),在不高于F的楼层扔鸡蛋不会碎,鸡蛋碎了不能再用,没碎可以继续使用,问不论F的大小(0<=F<=N),至少需要测量多少次才能测出F的大小.题意挺好理解的,鸡蛋少的话操作肯定多点,相当于行下往上测,鸡蛋比较多就可以使用类似二分的想法了. 思路1: dp+二分  时间复杂度O(K*N*log N),空间复杂度…

这是经典的扔鸡蛋的题目. 同事说以前在uva上见过,不过是扔气球.题意如下: 题意: 你有K个鸡蛋,在一栋N层高的建筑上,被要求测试鸡蛋最少在哪一层正好被摔坏. 你只能用没摔坏的鸡蛋测试.如果一个鸡蛋在上一次测试中没有被摔坏,那么你可以重复使用,否则,你只能用下一个鸡蛋. 需要求,最小的步数,使得你在这么多步内一定测试出结果. 思路: O(K * N^2) 首先,这个题比较绕.需要求一个最优决策使得步数最小,但是实际的步数是随着真实结果变化而变化的. 于是,为了保证在我们假设的步数内一定能够解完…

今天开始定期记录本人在leetcode上刷题时遇到的有意思的题目.   517. Super Washing Machines   You have n super washing machines on a line. Initially, each washing machine has some dresses or is empty. For each move, you could choose any m (1 ≤ m ≤ n) washing machines, and pass…

Write a program to find the nth super ugly number. Super ugly numbers are positive numbers whose all prime factors are in the given prime list primes of size k. Example: Input: n = 12, primes = [2,7,13,19] Output: 32 Explanation: [1,2,4,7,8,13,14,16,…

Write a program to find the nth super ugly number. Super ugly numbers are positive numbers whose all prime factors are in the given prime list primes of size k. For example, [1, 2, 4, 7, 8, 13, 14, 16, 19, 26, 28, 32] is the sequence of the first 12…

题目原文: Suppose that you have an n-story building (with floors 1 through n) and plenty of eggs. An egg breaks if it is dropped from floor T or higher and does not break otherwise. Your goal is to devise a strategy to determine the value of T given the…
