Question

How to get array subset in Go

Answer 1

package main

import "fmt"

func main() {
    arr := []int{3, 7, 9, 0, 4, 2, 1, 8}

    // Define start index and length of the subset
    startIndex := 2
    length := 4

    // Ensure the range is valid
    if startIndex + length > len(arr) {
        fmt.Println("Invalid range: Subset exceeds array bounds.")
        return
    }

    // Extract the subset using slicing
    subset := arr[startIndex : startIndex+length]

    fmt.Println("Subset:", subset)
}



/*
run:

Subset: [9 0 4 2]
