Ask the frog to jump on an n-level step with a total number of hops.Ideas* When N=1, there are 1 kinds of jumping method, f (1) = 1;* When n=2, there are 2 kinds of jumping method, F (2) = 2;* N=3, there are 3 kinds of jumping method, F (3) =3=f (3-1) +f (3-2) =f (2) +f (1);* N=4, there are 5 ki

Reprint Please specify: http://blog.csdn.net/ict2014/article/details/17394259 Skiplist is widely used in leveldb and lucence, and is a more efficient data structure. Because of its code and the simplicity of the implementation of the principle, it is more acceptable. Let's first look at the definition of skiplist and why it's called a jumping table. "Skip lists is data structures that use probabilistic balancing rather than strictly enforced balancing

Dynamic Programming Topic (II.)--Jumping steps1. Title DescriptionA step has a total of n levels, if you can jump 1 levels at a time, you can jump 2 levels.How many total hops are in total, and the time complexity of the algorithm is analyzed.2. Recursive methodFor this dynamic planning problem, we have two steps to think of: If we jump 1 levels, then the rest of the jump is f (n-1); If we jump 2 levels, then the rest of the jump is f (n-

A step has a total of n, if you can jump 1 levels at a time, you can also jump 2 levels, to find out how many kinds of jumping method.Problem Analysis:1F (n) = f (n1)=1n=1 2F (N) =1+1=2n=2When jumping a step for the first time, there is a way to do it when you first jump two steps .3F (N) =2+1=3n=3When you first jump a step there is f (3-1) in the method, when the first jump of two steps has f (3-2) in the

ProblemA frog can jump up to 1 steps at a time, or jump up to level 2. Ask the frog to jump on an n-level step with a total number of hops.IdeasWhen N=1, there is only one method of jumping, and f (1) = 1, when n=2, there are two kinds of jumping, and f (2) = 2, when n=3, you can jump from the n=1 directly to the n=3, can also jump from n=2 directly to N=3, and F (3) =f (1) +f (2) =3 ..., so you can use rec

C Language:1 /*2 -----------------------------------3 when n = 1, there are only 1 hops; when n = 2 o'clock, there are two kinds of jumps; when n = 3 o'clock, there are 3 kinds of jumps; when n = 4 o'clock, there are 5 methods of jumping; when n = 5 o'clock, there are 8 kinds of jumps4 so: Tiaofa (n)5 N=1, Tiaofa (1) = 16 n=2, Tiaofa (2) = 27 n>2, Tiaofa (n) = Tiaofa (n-1) + Tiaofa (n-2)8 -----------------------------------9 */Ten One# include A -

Title DescriptionA frog can jump up to 1 steps at a time, or jump up to level 2. Ask the frog to jump on an n-level step with a total number of hops.Thinking of solving problemsRecursion, from the previous step to this step the frog jumps a level or jumps two levels, the current number of steps is N, and the number of hops to the N-step is the sum of the number of n-1 and jumping n-2 steps. As you can see, this is a Fibonacci sequence .The end conditi

Skiplist is commonly used in various open source engines, such as Redis's SortedSet container, luence Index dictionary, and so on skiplist.1.SkipListInside the data structure, we know that there are two basic data storage structures: arrays and linked lists. They all have their own characteristics, arrays (especially ordered arrays), can be quickly queried, but not easy to delete operations, linked list, can be quickly deleted and deleted operations, but not easy to query. Is it possible that th

A frog can jump up to 1 steps at a time, or jump up to level 2 ... It can also jump on n levels. Ask the frog to jump on an n-level step with a total number of hops.Analysis:F (1) = 1F (2) = f (2-1) + f (2-2)//f (2-2) indicates the number of times the 2-step one-Hop 2-step.F (3) = f (3-1) + f (3-2) + f (3-3)...F (n) = f (n-1) + f (n-2) + f (n-3) + ... + f (n (n-1)) + f (n-n)Description1) Here the F (n) represents the number of N-step jumps,... n steps.2) n = 1 o'clock, there are only 1 methods o

A frog can jump up to 1 steps at a time, or jump up to level 2 ... It can also jump on n levels. Ask the frog to jump on an n-level step with a total number of hops.Because n steps, the first step has n kinds of jumping method: Jump 1 level, jump 2 level, to jump N levelJump 1 levels, leaving the n-1 level, then the jumping method is F (n-1)Jump 2 levels, leaving the n-2 level, then the

Because n steps, the first step has n kinds of jumping method: Jump 1 level, jump 2 level, to jump N levelJump 1 levels, leaving the n-1 level, then the jumping method is F (n-1)Jump 2 levels, leaving the n-2 level, then the jumping method is F (n-2)So f (n) =f (n-1) +f (n-2) +...+f (1)Because F (n-1) =f (n-2) +f (n-3) +...+f (1)So f (n) =2*f (n-1)public class So

PortalDescription House jumping, also known as plane jumping, is a world-class children's game and one of the traditional Chinese sports games. The game rules for house jumping are as follows: Determine a starting point on the ground, and draw $ N $ grids on the right of the starting point. These grids are all in the same line. Each grid has a number (integer), i

The jump table is an ordered data structure that supports the average O (logn) and worst O (N) complexity of node lookups. Jumping tables are applied to the scene of an ordered set key and a cluster node. This article refers to the Redis3.0 version of the source code, the comments refer to the Huang Jianhong comments, and add their own understanding. The definition of jumping tables and nodes is in redis.h,

55. Jumping GamesGiven a non-negative integer array, you are initially in the first position of the array. Each element in the array represents the maximum length that you can jump in that position. Determine if you can reach the last position.Example 1:Input: [2,3,1,1,4] Output: True explanation: Jump 1 steps from position 0 to 1, then jump 3 steps to reach the last position.Example 2:Input: [3,2,1,0,4] Output: false explanation: Anyway, you always g
