This is my first time go without hello world.

mode.go

package main

import (
        "fmt"
        "sort"
)

func mode(arr []int) int {
        sort.Ints(arr)
        var mode_count, mode_value, current_count, current_value int
        for _, a := range arr {
                if a != current_value {
                        current_value, current_count = a, 0
                }
                current_count++
                if mode_count < current_count {
                        mode_value, mode_count = current_value, current_count
                }
        }
        return mode_value
}

func main() {
        fmt.Println(mode([]int{1, 2, 2, 3, 3, 3, 2, 2}))
}
