# Java Program for Stooge Sort

The Stooge sort is a recursive sorting algorithm. It is defined as below (for ascending order sorting).

```Step 1 : If value at index 0 is greater than
value at last index, swap them.
Step 2:  Recursively,
a) Stooge sort the initial 2/3rd of the array.
b) Stooge sort the last 2/3rd of the array.
c) Stooge sort the initial 2/3rd again to confirm.
```

Output:

```1 2 3 4 5
```
