codes in these two methods that can abstract these different places and write them as a single, more general function? As shown below:Func Computeintarray (xs: [int]), [int] { var result: [int] = [] for x in xs { result.append (/* Something Using X */)} return result} To complete the above definition, we will need a new parameter to abstract out these different places:Func Computeintarray (xs: [int], f:int-i, int), [int] { var result: [int] = [] for x in xs { r

() function.5. GeneratorThe generator must be iterative and has better execution efficiency than the list. The representation is the {} that resolves the list to (). yeild keyword is the identity of the generator. The function return value is an object of a generator type, which is an iterator. We call a function that contains a yield statement as a generator. A builder is an iterator that is defined with normal function syntax.discover yield Besides being the generator's flag, there is also a

function, and the other is the Iterable,map function to the sequence.Each element and take the result as a new iteratorSee an example:def func (x): return x*xl=[1,2,3,4,5,6]Print (List (map (func,l)))The result of the output is:[1, 4, 9, 16, 25, 36]1.7Max () returns the maximum value1.8MIN () returns the minimum value1.9Next (Iterator[,default])Retrieves the next element in the iterator, if the default is given when the iteration of an object in the iterator is complete, then the call will play

[Basic ideas]Group records that originally had a large number of records. Cut into a number of sub-sequences, at this time each sub-sequence to sort the number of records is less, and then in these sub-sequences are directly inserted in the order, when the whole sequence is basically ordered. Then make a direct insert sort on the entire record.The so-called basic order, is the small keyword basic in front, large basic in the back, medium-sized basic in the middle. Like {2, 1, 3, 6, 4, 7, 5, 8, 9

Here's a second way to implement a one-to-one correlation mapping, the unique Foreign Key association.Unique FOREIGN Key Association: A Foreign Key association, which is intended to be used for many-to-one configurations, but can also be used to represent an affinity relationship if a unique limit is added.A unique foreign Key association is also used in two ways, one-way and two-way. The object model is consistent with the single-direction associated with the primary key, and the resulting rela
