values by comparing their original values.
In the example above, the type of the enum original value is int, so you just need to set the first original value. The remaining raw values are assigned in order. You can also use a string or a floating-point number as the original value of the enumeration.Use the Toraw and Fromraw functions to convert between the original value and the enumeration value.
If Let Convertedrank = Rank.fromraw (3) {
Let threedescription = Convertedrank.

Description: A class to dynamic to another class of functional objects before or after the modification, to add some additional functions; This is the decoration of the function of a class object, the decorated class with the decorated class, require the same Access interface method (function), which in the dynamic object-oriented class, generally to implement the same interface (interface) to constrain the implementation of the decoration class to have a reference
This chapter mainly describes how to activate some basic object operations in a special way, with the names of these special methods beginning with two underscores, with two underscore endings (such as GetItem), such as Obj[key] behind the getitem method, In order to obtain the value of My_collection[key], the interpreter actually invokes my_collection. GetItem (key).The example in this chapter is a stack of Python-style cards, very chewy.1.1 Card Instances
The first example 1-1 establishes a ca
time complexity of O (n). But the downside of bucket sequencing is:1) First, the space complexity is higher, the additional overhead is required. Sorting has two of the space cost of the array, one for the array to be sorted, and one is the so-called bucket, such as the value to be sorted from 0 to m-1, then need M bucket, this bucket array will be at least m space.2) The next element to be sorted must be within a certain range and so on.Bucket sorting is a sort of assignment. Assigning a sort
122 GB (NTFs format)18 GB Ubuntu partition (ext3 format)Linux switch partition 4GNow we need to adjust the Ubuntu partition from 18 GB to 20 GB. We need to take out 2 GB space from the partition where Vista is located, which involves the adjustment of NTFS partition. You can use gparted to adjust the size of the NTFS partition where Vista is located. However, it is not good to use gparted to adjust the NTFS partition, this is mainly because the adjustment function of ntfsprogs called by gparted

mirror. For girls, please use light makeup. For boys, please comb your hair and cut your beard. For details, refer to the resume photo standards. We have been trying to avoid looking at people by appearance. However, as long as I am a normal person, I cannot do it. The appearance of the image naturally determines the score you give, it is undeniable that under the same conditions, I will select a person with better image quality. from another perspective, can you trust me to take care of a job?
First look at an example: (from the big talk design mode) design pattern is obscure difficult to understand, personal feeling big talk design pattern on the example is closer to reality, can combine big talk design pattern and gof together to see.Example: A system for people to decorate clothes, similar to the display of QQ show, can have different styles of dressing. such as wearing underwear, suits, tie, boots, sneakers, etc., different styles of combination.If you define a subclass of people,

be referred to as comparison-based sorting;The cardinality sort first assigns the data elements to be sorted into different buckets, then "collects" the data elements in each bucket.By using this method of "assigning" and "collecting" to sort multiple keywords, the cardinality sort implements the ordering of multiple keywords.———————————————————————————————————————Cases:Each card has two "keywords": Suit and face value. The order of size is:Suit: §Fa

number of each service can be as high as hundreds of thousands of, they do not occur frequently in the case of a suit. The game is more game strategy design, encourage players to spend money to take a shortcut overdraft game life cycle, or even a few days to dominate a server. So that other players can not catch up, even if the cost of money chasing is very low, it is better to enter a new service to start again. This led to a new service, players ar
