Logic:
1. Normally we use sort() or sorted() to arrange a list
→ Example: [5, 2, 8, 1, 3]
2. But here, we must sort WITHOUT using those Metg.
3. Approach → Use a simple sorting algorithm like Bubble Sort.
4. Bubble Sort Logic:
a. Start with the first element and compare it with the next.
b. If the first is greater than the second → swap them.
c. Repeat for the whole list → largest element “bubbles up” to the end.
d. Repeat this process for the remaining elements until the list is sorted.
5. At the end → we get the sorted list.
Code:
Sort a list using bubble sort
numbers = [5, 2, 8, 1, 3]
n = len(numbers)
for i in range(n):
for j in range(0, n - i - 1):
if numbers[j] (Greater then symbol) numbers[j + 1]:
swap
numbers[j], numbers[j + 1] = numbers[j + 1], numbers[j]
print("Sorted list is:", numbers)
Alternative method: Using min() repeatedly
numbers = [5, 2, 8, 1, 3]
sorted_list = []
while numbers:
minimum = min(numbers) # find smallest
sorted_list.append(minimum)
numbers.remove(minimum) # remove smallest
print("Sorted list is:", sorted_list)
