I have a kinda big file which looks like this:

```
100]
Armor=769       
101]
Armor=769       
102]
Armor=769       
103]
Armor=772       
104]
Armor=772       
108]
Armor=770       
109]
Armor=773       
110]
Armor=773       
114]
Armor=771       
115]
Armor=774       
116]
Armor=774       
242]
Armor=778       
243]
Armor=779   

```

I've already been playing around with notepad++, that's how I got this result , but now I am STUCK. What i want is: Add to every second line a [ , so `100]`, `101]` and `102]` are now enclosed in brackets. I can't just search for "1" and replace with [1 , the numbers are random, and get a lot bigger. I guess I have to go with regex here, which is a problem, because I have no idea how!
