Aggregates the results of applying an operator to subsequent elements.
Aggregates the results of applying an operator to subsequent elements.
This is a more general form of fold and reduce. It has similar semantics, but does
not require the result to be a supertype of the element type. It traverses the elements in
different partitions sequentially, using seqop to update the result, and then
applies combop to results from different partitions. The implementation of this
operation may operate on an arbitrary number of collection partitions, so combop
may be invoked arbitrary number of times.
For example, one might want to process some elements and then produce a Set. In this
case, seqop would process an element and append it to the list, while combop
would concatenate two lists from different partitions together. The initial value
z would be an empty set.
pc.aggregate(Set[Int]())(_ += process(_), _ ++ _)
Another example is calculating geometric mean from a collection of doubles (one would typically require big doubles for this).

The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

Returns a parallel implementation of this collection.
For most collection types, this method creates a new parallel collection by copying
all the elements. For these collection, par takes linear time. Mutable collections
in this category do not produce a mutable parallel collection that has the same
underlying dataset, so changes in one collection will not be reflected in the other one.

behaviour by creating a parallel collection which shares the same underlying dataset.
For these collections, par takes constant or sublinear time.

All these operations apply to those elements of this string which
satisfy the predicate p.
[use case] Returns a string formed from this string and another iterable collection by combining corresponding elements in pairs.
Returns a string formed from this string and another iterable collection by combining corresponding elements in pairs. If one of the two collections is longer than the other, its remaining elements are ignored.
the type of the second half of the returned pairs
The iterable providing the second half of each result pair
a new collection of type That containing pairs consisting of
corresponding elements of this string and that. The length
of the returned collection is the minimum of the lengths of this string and that.
Returns a string formed from this string and another iterable collection by combining corresponding elements in pairs.
Returns a string formed from this string and another iterable collection by combining corresponding elements in pairs. If one of the two collections is longer than the other, its remaining elements are ignored.
the type of the first half of the returned pairs (this is always a supertype
of the collection's element type A).
the type of the second half of the returned pairs
the class of the returned collection. Where possible, That is
the same class as the current collection class Repr, but this
depends on the element type (A1, B) being admissible for that class,
which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That].
is found.
The iterable providing the second half of each result pair
an implicit value of class CanBuildFrom which determines the
result class That from the current representation type Repr
and the new element type (A1, B).
a new collection of type That containing pairs consisting of
corresponding elements of this string and that. The length
of the returned collection is the minimum of the lengths of this string and that.
[use case] Returns a string formed from this string and another iterable collection by combining corresponding elements in pairs.
Returns a string formed from this string and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.
the iterable providing the second half of each result pair
the element to be used to fill up the result if this string is shorter than that.
the element to be used to fill up the result if that is shorter than this string.
a new collection of type That containing pairs consisting of
corresponding elements of this string and that. The length
of the returned collection is the maximum of the lengths of this string and that.
If this string is shorter than that, thisElem values are used to pad the result.
If that is shorter than this string, thatElem values are used to pad the result.

If that is shorter than this string, thatElem values are used to pad the result.
[use case] Zips this string with its indices.
Zips this string with its indices.
A new collection of type That containing pairs consisting of all elements of this
string paired with their index. Indices start at 0.
Zips this string with its indices.
Zips this string with its indices.
the type of the first half of the returned pairs (this is always a supertype
of the collection's element type A).
the class of the returned collection. Where possible, That is
the same class as the current collection class Repr, but this
depends on the element type (A1, Int) being admissible for that class,
which means that an implicit instance of type CanBuildFrom[Repr, (A1, Int), That].
is found.
A new collection of type That containing pairs consisting of all elements of this
string paired with their index. Indices start at 0.

p(x, y) is true for all corresponding elements x of this string
and y of that, otherwise false.
