package main

import (
	"bufio"
	"fmt"
	"os"
)

var reader *bufio.Reader = bufio.NewReader(os.Stdin)
var writer *bufio.Writer = bufio.NewWriter(os.Stdout)

func printf(f string, a ...interface{}) { fmt.Fprintf(writer, f, a...) }
func scanf(f string, a ...interface{})  { fmt.Fscanf(reader, f, a...) }

func main() {
	defer writer.Flush()
}

Usage

I create a new directory with the problem number and problem name using the following format {problem_number}_{problem_name}. Create a file named {problem_number}. I create a test for each problem to test the code.

Helpers

• Use %v to print array. Example: fmt.Printf("%v", projects)
• Create empty map make(map[int]int), map[rune]bool{}
• Create empty rune make([]rune, 5) // with size, map[rune]bool{}
• Sort list/slice slices.Sort(mySlice).
• Sort with comparer sort.Slice(mySlice, func(i, j int) bool { return mySlice[i] > mySlice[j] })
• Deep compare array reflect.DeepEqual([]int{0, 1, 1}, []int{0, 1, 1})
