go-number-filter's Introduction

Go Number Filter

Go Number Filter is an program that provides various ways to filter an given array of numbers It uses builder pattern to nest multiple filters. program supports all or any filter type

Features

Filters (even, odd, prime, multiplOf, lesserThan, greaterThan, custom)
Filters can be of ALL or ANY type
Can nest muiltiple patterns

How to use

clone this repository [git clone https://github.com/PratikJethe/go-number-filter.git]
to run program [go run .]

Examples

1. isEven Filter

    sampleInput := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
	numberFilter := getNewFilter(sampleInput)
	// even
	fmt.Println(numberFilter.isEven().filterAll())

	//TERMINAL
	$ go run .
    [2 4 6 8 10 12 14 16 18 20]

2. Nesting Multiple Filters

    sampleInput := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
	numberFilter := getNewFilter(sampleInput)
	// even prime
	fmt.Println(numberFilter.isEven().isPrime().filterAll())

	//TERMINAL
	$ go run .
    [2]

3. Custom Filter Function

    sampleInput := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
	numberFilter := getNewFilter(sampleInput)
	//custom
	fmt.Println(numberFilter.custom(func(number int) bool {
	 return number > 5 && number < 10
	}).filterAll())

	//TERMINAL
	$ go run .
    [6 7 8 9]

4. All Type Filter

    sampleInput := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
	numberFilter := getNewFilter(sampleInput)
	//ALL type
	fmt.Println(numberFilter.isGreaterThan(10).isPrime().filterAll())

	//TERMINAL
	$ go run .
    [11 13 17 19]

5. Any Type Filter

    sampleInput := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
	numberFilter := getNewFilter(sampleInput)
	//ALL type
	fmt.Println(numberFilter.isGreaterThan(10).isPrime().filterAny())

	//TERMINAL
	$ go run .
    [2 3 5 7 11 12 13 14 15 16 17 18 19 20]
