You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fibonacci_memoization.go
    path of file: ./repos/the-way-to-go_ZH_CN/eBook/examples/chapter_6
    
    the code of the file until where you have to start completion: // fibonacci_memoization.go
package main

import (
	"fmt"
	"time"
)

const LIM = 41

var fibs [LIM]uint64

func main() {
	var result uint64 = 0
	start := time.Now(
    
func main() {
	var result uint64 = 0
	start := time.Now()
	for i := 0; i < LIM; i++ {
		result = fibonacci(i)
		fmt.Printf("fibonacci(%d) is: %d\n", i, result)
	}
	end := time.Now()
	delta := end.Sub(start)
	fmt.Printf("longCalculation took this amount of time: %s\n", delta)
}
