Question

Explain how to write the selection sort function, assuming the swap was written outside the function?

Answer 1

To write a selection sort function, you can write a loop to iterate through each element of the array, and within that loop, another loop to find the minimum element from the unsorted part. If the swap operation is written outside the function, you can perform the swap when the minimum element is found.

Step-by-step explanation:

Selection Sort Function

Selection sort is a sorting algorithm that works by repeatedly finding the minimum element from the unsorted part of the array and putting it at the beginning. If the swap operation is written outside the function, you can write a selection sort function in the following way:

def selection_sort(arr):
n = len(arr)
for i in range(n):
min_idx = i
for j in range(i+1, n):
if arr[j] < arr[min_idx]:
min_idx = j
if min_idx != i:
arr[i], arr[min_idx] = arr[min_idx], arr[i]

This function takes an array arr as input and sorts it using the selection sort algorithm. The outer loop iterates over each element of the array and the inner loop finds the minimum element from the unsorted part.
