Selection Sort

Detailed guide and Python implementation for the 'Selection Sort' problem.

問題提起

簡単

Write a function selection_sort(arr) that sorts a list of integers arr in ascending order using the Selection Sort algorithm and returns the sorted list.

制約
  • 0 <= len(arr) <= 500
  • -10^4 <= arr[i] <= 10^4

Example 1
Input
arr = [64, 25, 12, 22, 11]
Output
[11, 12, 22, 25, 64]
Explanation

We repeatedly find the minimum element from the unsorted part and swap it with the beginning.

Need a Hint?
Consider using Sorting-specific data structures like sets or heaps.
Edge Cases to Watch
  • Empty input structures
  • Single element inputs
  • Large numerical bounds
