Example

1. Create a plain source code.

package main

import (
	"fmt"
	"strings"
)

func Solve(n int) string {
	str := make([]string, n)
	content := byte('*')

	for i := 0; i < n; i++ {

		line := make([]byte, n-i)
		for j := 0; j < len(line); j++ {
			line[j] = content
		}

		str[i] = string(line)
	}

	return strings.Join(str, "\n")
}

func main() {
	var n int
	fmt.Scanf("%d", &n)
	out := Solve(n)
	fmt.Println(out)
}

2. Encode the plain source code into a base64 string.

3. Create a JSON file as a request body. (request.json)

4. Make an HTTP request.

curl -XPOST -d @request.json http://localhost:8000/api/v1/exec

5. Response body.
