How to enable or disable garbage collection at runtime using runtime.GC()?

To enable or disable garbage collection at runtime using runtime.GC(), you can use the SetGCPercent(percent int) function from the runtime package in Go. Here's how you can do it:

To enable garbage collection:

Import the runtime package: import "runtime"
Call runtime.SetGCPercent(-1) to set the garbage collection percentage to the default value.

To disable garbage collection:

Import the runtime package: import "runtime"
Call runtime.SetGCPercent(-1) to set the garbage collection percentage to -1, effectively disabling garbage collection.

Here's an example:

package main

import (
	"fmt"
	"runtime"
)

func main() {
	// Enable garbage collection
	runtime.SetGCPercent(-1)

	// Your code here...

	// Disable garbage collection
	runtime.SetGCPercent(100)

	// Your code here...
}

Note: Disabling garbage collection is generally not recommended unless you have a specific reason to do so. The Go runtime manages garbage collection automatically, and it's typically best to let it handle memory management for you.
