Functions

func Contains

func Contains(slice []int, s int) bool

Checks if given integer exists in the slice.

func Cumsum

func Cumsum(slice []int) []int

Calculates a slice of cumulative sum from given slice.

func Delta

func Delta(ints []int) []int

Returns the delta between all consecutive ints. Returned slice length is one item shorter.

func Diff

func Diff(a, b []int) []int

Finds the difference in elements between slice A and slice B ; ie. A-B

func FindIndex

func FindIndex(slice []int, val int) (int, bool)

Finds the index of first occurrence of the given value and returns the index and a boolean. Boolean is true when index is found, otherwise index = -1.

func FindMissingIndexes

func FindMissingIndexes(newslice []int, slice []int) (idx []int)

Compares <newslice> against <slice>. Those numbers' indexes from <slice> are collected which are not found from <newslice>.

func GetIndex

func GetIndex(slice []int, val int) int

Finds the index of first occurrence of the given value and returns the index. If not found index = -1.

func Insert

func Insert(slice []int, idx int, val int) []int

Insert inserts given value to given index into a slice

func Max

func Max(a int, b int) int

Returns the larger of given integers.

func Min

func Min(a int, b int) int

Returns the smaller of given integers.

func NumRange

func NumRange(start int, end int, step int) (numberrange []int)

Returns an evenly spaced slice of integers, between <start> and <end> with spacing <step>.

func RandRange

func RandRange(min int, max int) int

Creates a random integer between min and max value.

func Remove

func Remove(slice []int, s int) []int

Removes first occurence of given integer from a slice.

func RemoveFrom

func RemoveFrom(slice []int, s int) []int

RemoveFrom removes an integer from given index

func ReplaceNil

func ReplaceNil(val int, i *int) int

Replaces nil valued *int with given integer

func Select

func Select(condition bool, i1, i2 int) int

Returns i1 if condition == TRUE, else returns i2

func SetDefault

func SetDefault(defaultval int, confval int) int

Replaces default value for a parameter, if the configuration value is zero (ie. initialized empty variable). Note that the function does not make any difference, if the configuration is set to zero on purpose.

func SliceOf

func SliceOf(value int, size int) []int

SliceOf creates a slice of given size filled with value.

func SwitchIf

func SwitchIf(condition bool, i1, i2 int) (int, int)

Returns the given values without changes, if condition == FALSE. Returns the values in switched order, if condition == TRUE.

func Unique

func Unique(t []int) []int

Returns unique integers from given slice.
