Set operations The main set operations are (basic ADT operations)... insert (T data): Insertdatato set erase (cons T data): Deletesdatafrom the set bool empty(): Checks for set to be empty find(const T data): finds whetherdatais present in the set or not ...
The structure unordered set uses hashing, and its operations work inO(1)timeon average. The choice of whichset implementationto use is often a matter of taste. The benefit of the set structure is that it maintains the order of the elements and provides functions that are not available in un...
Creates a set of lengthlast - first, filled with all values obtained by dereferencing theInputIteratorson the range[first, last). If the function objectcompis supplied, it is used to compare elements of the set. Otherwise, the default function object in the template argument is used. The te...

std::setis an associative container that contains a sorted set of unique objects of typeKey. Sorting is done using the key comparison functionCompare. Search, removal, and insertion operations have logarithmic complexity. Sets are usually implemented asRed–black trees. ...
Handle to object containing sparse matrix and other internal data for subsequent Sparse BLAS operations. nrows Number of rows of the input matrix. ncols Number of columns of the input matrix. nnz Number of non-zero elements in the input matrix. index Indicates how input arrays are indexe...
In this chapter we will introduce how sets are declared and initialized. More advanced set concepts, such as assignments to sets, and lag and lead operations are covered in the chapters Dynamic Sets and Sets as Sequences. The topics discussed in this chapter will be enough to provide a good...

Search, removal, and insertion operations have logarithmic complexity. Sets are usually implemented as Red–black trees.Everywhere the standard library uses the Compare requirements, uniqueness is determined by using the equivalence relation. In imprecise terms, two objects a and b are considered ...
