func AllOf ¶

func AllOf[T any](elems []T, pred func(elem T) bool) bool

AllOf returns true if and only if all of the elements in the slice satisfy the given predicate.

func AnyOf ¶

func AnyOf[T any](elems []T, pred func(elem T) bool) bool

AnyOf returns true if and only if at least one of the elements in the slice satisfy the given predicate.

func BinarySearch ¶

func BinarySearch[T constraints.Ordered](elems []T, target T) (index int)

BinarySearch returns the index of the given target in the provided sorted elems slice. If the target is not in the sorted slice, -1 is returned.

func CountIf ¶

func CountIf[T any](elems []T, pred func(elem T) bool) (count int)

CountIf returns the number of elements in the slice that satisfy the given predicate.

func Filter ¶

func Filter[T any](elems []T, p func(T) bool) (r []T)

Filter returns all elements that satisfy the given predicate in a new slice.

func FilterNot ¶

func FilterNot[T any](elems []T, p func(T) bool) (r []T)

Filter returns all elements that do NOT satisfy the given predicate in a new slice.

func FindIf ¶

func FindIf[T any](elems []T, pred func(elem T) bool) int

FindIf returns the index to the first element in the slice that satisfies the given predicate. If no such element exists, -1 is returned.

func Map ¶

func Map[T any, U any](elems []T, f func(T) U) (r []U)

Map applies the given function to each slice element and returns the resultant slice.

func Max ¶

func Max[T constraints.Ordered](x, y T) T

func Merge ¶

func Merge[T constraints.Ordered](left, right []T) (sorted []T)

Merge merges the two provided sorted slices into a single sorted slice.

func Min ¶

func Min[T constraints.Ordered](x, y T) T

func NoneOf ¶

func NoneOf[T any](elems []T, pred func(elem T) bool) bool

NoneOf returns true if and only if none of the elements in the slice satisfy the given predicate.

func ProdSlice ¶

func ProdSlice[T constraints.Integer | constraints.Float](elems []T) T

ProdSlice returns the product of all the elemenst in the given slice. No attempt is made to detect overflow.

func Reduce ¶

func Reduce[T any, U any](elems []T, f func(a U, b T) U, initial U) (r U)

Reduce reduces the given slice to a single value using the given function and initial value.

func SumSlice ¶

func SumSlice[T constraints.Ordered](elems []T) T

SumSlice returns the sum of all the elements in the given slice. No attempt is made to detect overflow.
