I have below output from a text file. This is long file i just copy here some rows only.

```
HP83904B74E6
13569.06
7705.509999999999
HP4DC2EECAA8
4175.1
2604.13

```

And i want to print it like below. 

```
HP83904B74E6     13569.06      7705.509999999999
HP4DC2EECAA8     4175.1        2604.13

```

I have tried by reading the file line by live using while loop and try to store the value of variable e.g. `variablename$i` so that i can print it like `variablename0` and after every 3 line i have used If statement to print the value of variablename0 variablename1 variablename2, but did not work for me.
