How is the process of reverse memory release implemented within the system?

In Go, the process of memory management is implemented through an integrated garbage collector. It automatically tracks objects in memory that are no longer used by the program and frees them.

The main stages of the garbage collector:

1. Mark — the collector traverses all active references and marks the objects that can be reached.
2. Sweep — objects that were not marked are considered unused and are freed.

This occurs in the background, without requiring manual memory management from the developer, which reduces the likelihood of errors related to memory leaks or double freeing.

Example of memory usage in Go:

package main

import "fmt"

func main() {
    data := make([]int, 1000000) // allocate memory
    fmt.Println(len(data))
    // After exiting the function, data will become inaccessible and will be cleaned up by the garbage collector
}

Here, the memory for the slice data will be automatically freed when it is no longer referenced.
