What will the program output when executed? package main import "fmt" func main() { s := make([]int, 0, 3) m := map[string]int{"a": 1, "b": 2} for i := 0; i < 5; i++ { s = append(s, i) } fmt.Println(len(s), cap(s)) if v, ok := m["c"]; ok { fmt.Println(v) } else { fmt.Println("no key") } }

The program creates a slice s with length 0 and capacity 3, then adds 5 elements (0,1,2,3,4) to it. When adding elements, the slice automatically expands if the capacity is exceeded.

After the loop:

• len(s) will be 5 (number of elements)
• cap(s) will be 6, because when the capacity of a slice is exceeded, it usually doubles (from 3 to 6)

Next, the program tries to get the value for the key "c" from the map m. Since there is no such key, ok will be false and "нет ключа" will be printed.

Final output:

5 6
нет ключа
