Unzip splits a slice of tuples into two separate slices. The inverse operation of Zip. Useful for separating paired data.
package main
import (
"fmt"
u "github.com/rjNemo/underscore"
)
func main() {
// Basic usage
pairs := []u.Tuple[int, string]{
{Left: 1, Right: "a"},
{Left: 2, Right: "b"},
{Left: 3, Right: "c"},
}
nums, letters := u.Unzip(pairs)
fmt.Println(nums) // [1, 2, 3]
fmt.Println(letters) // ["a", "b", "c"]
// Use case: separating keys and values
keyValuePairs := []u.Tuple[string, int]{
{Left: "apple", Right: 5},
{Left: "banana", Right: 3},
{Left: "cherry", Right: 8},
}
items, counts := u.Unzip(keyValuePairs)
fmt.Println("Items:", items) // Items: [apple banana cherry]
fmt.Println("Counts:", counts) // Counts: [5 3 8]
// Empty slice
emptyNums, emptyStrs := u.Unzip([]u.Tuple[int, string]{})
fmt.Println(emptyNums, emptyStrs) // [] []
}
