A frog can jump up to 1 step or 2 steps at a time ... It can also jump up to N steps.Find out how many jumping methods the frog can use to jump up an n-step.

, Preconditions, precondition judgment No Additional Parameters: No Error Messages in Thrown Exceptions;There is an Object object as an extra parameter: the thrown exception uses Object.toString () as the error message;There is a String Object as an extra parameter, and there is a set of any number of additional Object objects: this variant handles exception messages a bit like printf, but only supports the %s indicator considering GWT compatibility and

Brief introduction of the project projectRecurrent Neural Networks with Word EmbeddingsTutorial Address: http://deeplearning.net/tutorial/rnnslu.htmlTaskThe slot-filling (spoken language understanding) assigns labels to each word in a sentence, which is a classification problem.DatasetThe data set is a small data set of DARPA: ATIS (Airline Travel Information System), expressed by Inside Outside Beginning (IOB)There are 4,978 sentences word 56590 words in the training set of data set.Test set has 893 sentences and word

In normal code development, collection classes are often used, such as ArrayList for list cache, Map for mapping, etc Recently, I have focused on the hierarchical inheritance relationship and internal storage structure of the next java collection class, making a summary so that I can turn it over at any time later. java collections, whether List, Set, or Map, are inherited from the collection interface, which mainly defines some public
Preface: Collection class is a common Base Class Library, and it is a way for java to save objects.It is precisely because they are often used more frequently and speak in a masterful way that it is of great benefit to sum up and summarize them.
One. Two Ancestor Interfaces
1）Conllection。A sequence of independent elements, the elements of which are subject to one or more rules, all single-column collection classes implement their interfaces, such as List,Set,Queue.
