Functions ¶
func Dedupe ¶
Dedupe returns n, the number of distinct elements in data. The resulting elements are sorted in elements [0, n) or data[:n] for a slice.
Example ¶
a := []int{4, 1, 2, 1, 3, 4, 2}
fmt.Println(a[:Dedupe(sort.IntSlice(a))])
b := []string{"foo", "bar", "baz", "bar", "foo", "qux", "qux"}
fmt.Println(b[:Dedupe(sort.StringSlice(b))])
Output: [1 2 3 4] [bar baz foo qux]
func SearchBytes ¶
SearchBytes searches for x in a sorted slice of bytes and returns the index as specified by sort.Search. The slice must be sorted in ascending order.
func SearchFloat32s ¶
SearchFloat32s searches for x in a sorted slice of float32 and returns the index as specified by sort.Search. The slice must be sorted in ascending order.
