Go-Solve-Kit

Designed specifically for programming problem solving.

It's like VB LINQ, JavaScript array Function ... more.

Install

$ go get github.com/laijunbin/go-solve-kit

Import

import (
	sk "github.com/laijunbin/go-solve-kit"
)

Example

Example 1: two number sum.
func main() {
	sum := sk.LineInput().Split(" ")[:2].ToIntArray().Sum()
	fmt.Println(sum)
}
Example 2:
func main() {
	nums := []int {1, 2, 3, 4, 5}
	output := sk.FromIntArray(nums).Map(func(v sk.Int, _ int) interface{} {
		return v * v
	}).Filter(func(v sk.Type, _ int) bool {
		return v.ToInt() % 2 == 0
	}).ToStringArray().Join("\n")
	fmt.Println(output)
}

Output:

4
16
Example 3:
func main() {
	array2D := sk.NewArray(5).Map(func(_ sk.Type, i int) interface{} {
		return sk.NewRange(1, 5, 2).Map(func(v sk.Int, j int) interface{} {
			return v.ValueOf() * i
		})
	})
	fmt.Println(array2D)
	fmt.Println(array2D.Get(2, 2).ToInt())
	fmt.Println(array2D.Get(4, 1).ToInt())
	fmt.Println("-------------------")
	fmt.Println(array2D)
	fmt.Println(array2D.Length())
	fmt.Println(array2D.Flatten())
	fmt.Println(array2D.Flatten().Length())
}

Output:

[{[{0} {0} {0}]} {[{1} {3} {5}]} {[{2} {6} {10}]} {[{3} {9} {15}]} {[{4} {12} {20}]}]
