Python Program for Stooge Sort
• Last Updated : 30 Dec, 2020

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.
```

## Python3

 `# Python program to implement stooge sort`` ` `def` `stoogesort(arr, l, h):``    ``if` `l >``=` `h:``        ``return``  ` `    ``# If first element is smaller``    ``# than last,swap them``    ``if` `arr[l]>arr[h]:``        ``t ``=` `arr[l]``        ``arr[l] ``=` `arr[h]``        ``arr[h] ``=` `t``  ` `    ``# If there are more than 2 elements in``    ``# the array``    ``if` `h``-``l``+``1` `> ``2``:``        ``t ``=` `(``int``)((h``-``l``+``1``)``/``3``)``  ` `        ``# Recursively sort first 2/3 elements``        ``stoogesort(arr, l, (h``-``t))``  ` `        ``# Recursively sort last 2/3 elements``        ``stoogesort(arr, l``+``t, (h))``  ` `        ``# Recursively sort first 2/3 elements``        ``# again to confirm``        ``stoogesort(arr, l, (h``-``t))``  ` ` ` `# deriver ``arr ``=` `[``2``, ``4``, ``5``, ``3``, ``1``]``n ``=` `len``(arr)`` ` `stoogesort(arr, ``0``, n``-``1``)``  ` `for` `i ``in` `range``(``0``, n):``    ``print``(arr[i], end ``=` `\``' \'``)`` ` `# Code Contributed by Mohit Gupta_OMG <(0_o)>`

Output:

```1 2 3 4 5
```
