Solution 1
The complexity of Bubble sort is O(n^2).
Solution 2
The complexity of Bubble sort is O(n^2). This is because Bubble sort has to go through the entire list for each item, so in the worst case scenario (where the list is in reverse order), it would have to make n comparisons for the first item, n-1 for the second, and so on. This results in a time complexity of (n*(n-1))/2, which simplifies to O(n^2).
