I have attended an Interview Yesterday, I don't find the solution of an given problem below.
How to sort an int array with starting 3 digits numbers and remaining 2,1,4,5 etc digits.

Ex:-Input is 

```
i={1,34,323,456,5432,34566,33,45,654}

```

output is,

```
i={323,456,654,1,34,33,45,5432}

```
