// You have a slice that contains Beatles' awesome song:

// Yesterday. You want to add newlines after each sentence.

// Your goal is creating a new slice, then copying
|
||||
// each sentence of the lyric to the new buffer, then
|
||||
// after each sentence adding a newline character.
|

// So, create a new slice and copy every words into it. Lastly,

// after each sentence, add a newline character ('\n').

// RESTRICTION EXPLANATION:

//
|

// Do not use slicing for printing the sentences.

//
|

// fmt.Println(lyric[:8])

// fmt.Println(lyric[8:18])

||||
// You need to put each lyric sentence
|
||||
// + a newline character into this buffer

||||
//

||||

// fix := make(...)

||||
// #2: CALCULATE THE CUT POINTS
|
||||
//
|
||||
// You want to put newlines after each sentence. So you may want to put
|
||||
// these index positions into a slice. Then you can use them to cut the
|
||||
// lyric slice.

||||

||||
// cutpoints := []int{...}

|
||||
//

||||
|
||||
// for ... {
|
||||
// Use the `copy` function to copy from the `lyric` slice to the buffer.
