## zipstring

### Instructions

Write a function that takes a `string` and returns a new `string` that replaces every character with the number of duplicates and the character itself, deleting the extra duplications.

- The letters are from the latin alphabet list only. Any other character, symbols, shall not be tested.

### Expected function

```go
func ZipString(s string) string {

}
```

### Usage

Here is a possible program to test your function:

```go
package main

import (
	"fmt"
)

func main() {
	fmt.Println(ZipString("YouuungFellllas"))
	fmt.Println(ZipString("Thee quuick browwn fox juumps over the laaazy dog"))
	fmt.Println(ZipString("Helloo Therre!"))
}
```

And its output:

```console
$ go run .
