Quick Note

Iterating over map:

for k, v := range m { 
    fmt.Printf("key[%s] value[%s]\n", k, v)
}
or

for k := range m {
    fmt.Printf("key[%s] value[%s]\n", k, m[k])
}

Declaration of Map:

  m := make(map[int]bool)

To get the data from map

  m[121]

Linked List

Creation:

list.New() 

Accessing element from the list:

type Node struct {
  row int
  col int
}

for e := l.Front(); e != nil; e = e.Next() {
		row := e.Value.(*Node).row
		col := e.Value.(*Node).col
}
