# Python: Strange sort of list of numbers

## Python Programming Puzzles: Exercise-97 with Solution

Write a Python program to find the following strange sort of list of numbers: the first element is the smallest, the second is the largest of the remaining, the third is the smallest of the remaining, the fourth is the smallest of the remaining, etc.

Input: [1, 3, 4, 5, 11] Output: [1, 11, 3, 5, 4] Input: [27, 3, 8, 5, 1, 31] Output: [1, 31, 3, 27, 5, 8] Input: [1, 2, 7, 3, 4, 5, 6] Output: [1, 7, 2, 6, 3, 5, 4]

**Sample Solution:**

**Python Code:**

```
# License: https://bit.ly/3oLErEI
# Function to perform a strange sorting on a list of numbers
def test(nums):
# If the list has less than 2 elements, return the list as it is
if len(nums) < 2:
return nums
# Initialize an empty result list to store the sorted numbers
result = []
# Iterate through the first half of the list
for i in range(len(nums)//2):
# Append the minimum value to the result
result.append(min(nums))
# Remove the minimum value from the list
nums.remove(min(nums))
# Append the maximum value to the result
result.append(max(nums))
# Remove the maximum value from the list
nums.remove(max(nums))
# If there is one element left in the list, append it to the result
if len(nums) > 0:
result.append(nums[0])
# If the result list is still smaller than twice the length of the original list,
# extend it with the remaining elements from the original list
if len(result) < 2 * len(nums):
result.extend(nums[len(result) // 2 + 1:len(result) // 2 + 1 + len(nums) - len(result)])
# Return the final sorted list
return result
# Test cases with different lists of numbers
nums = [1, 3, 4, 5, 11]
print("Original list of numbers:")
print(nums)
print("Strange sort of list of said numbers:")
print(test(nums))
nums = [27, 3, 8, 5, 1, 31]
print("\nOriginal list of numbers:")
print(nums)
print("Strange sort of list of said numbers:")
print(test(nums))
nums = [1, 2, 7, 3, 4, 5, 6]
print("\nOriginal list of numbers:")
print(nums)
print("Strange sort of list of said numbers:")
print(test(nums))
```

Sample Output:

Original list of numbers: [1, 3, 4, 5, 11] Strange sort of list of said numbers: [1, 11, 3, 5, 4] Original list of numbers: [27, 3, 8, 5, 1, 31] Strange sort of list of said numbers: [1, 31, 3, 27, 5, 8] Original list of numbers: [1, 2, 7, 3, 4, 5, 6] Strange sort of list of said numbers: [1, 7, 2, 6, 3, 5, 4]
