Golang assignment 8

In the below code snippet concurrent goroutines execution corrupts a piece of data by accessing it simultaneously it leads in raise condition.

Code snippet output when you run this : 1 is Even
Solution snipped output once code is corrected: 0 is Even

Snippets are available in the doc attached below

package main

import (
"fmt"
"time"
)

func isEven(n int) bool {
return n%2 == 0
}

func main() {
n := 0

go func() {
	nIsEven := isEven(n)
	time.Sleep(5 * time.Millisecond)
	if nIsEven {
		fmt.Println(n, " is even")
		return
	}
	fmt.Println(n, "is odd")
}()

go func() {
	n++
}()

// just waiting for the goroutines to finish before exiting
time.Sleep(time.Second)

}

instead of passing mutex as param and calling Lock here, keep it at caller go-routine. passing it here doesn't solves the original issue. sorry, didn't realize this earlier.
