How to work with go mutex
```go
package main
import (
"fmt"
"sync"
)
type Memory[T any] struct {
Data []T
Mutex sync.Mutex
}
func NewMemory[T any]() (*Memory[T], error) {
mem := Memory[T]{
Data: make([]T, 0),
}
return &mem, nil
}
func (mem *Memory[T]) Append(data T) {
mem.Mutex.Lock()
mem.Data = append(mem.Data, data)
mem.Mutex.Unlock()
}
func (mem *Memory[T]) Display() {
for _, item := range mem.Data {
fmt.Println(item)
}
}
func main() {
memory, _ := NewMemory[string]()
terminator := make(chan string, 0)
runner := func(procId string, mem *Memory[string]) {
defer func() {
terminator <- ""
}()
for i := 0; i < 5; i++ {
item := fmt.Sprintf("PID[%s]: %d", procId, i)
mem.Append(item)
}
}
go runner("1", memory)
go runner("2", memory)
go runner("3", memory)
j := 0
for {
if j >= 3 {
break
}
select {
case _ = <-terminator:
j++
}
}
memory.Display()
```
