Sorting: Bubble Sort
Consider the following version of Bubble Sort:
for (int i = 0; i < n; i++) {
for (int j = 0; j < n - 1; j++) {
// Swap adjacent elements if they are in decreasing order
if (a[j] > a[j + 1]) {
swap(a[j], a[j + 1]);
}
}
}
Task Given an n-element array, A=a[0],a[1],...,a[n-1] of distinct elements, sort array A in ascending order using the Bubble Sort algorithm above. Once sorted, print the following three lines:
- Array is sorted in numSwaps swaps, where numSwaps is the number of swaps that took place.
- First Element: firstElement, where firstElement is the first element in the sorted array.
- Last Element: lastElement, where lastElement is the last element in the sorted array.
Hint: To complete this challenge, you must add a variable that keeps a running tally of all swaps that occur during execution.
Input Format
The first line contains an integer, n, denoting the number of elements in array A. The second line contains n space-separated integers describing the respective values of a[0],a[1],...,a[n-1].
Constraints
- 2 <= n <= 600
- 1 <= a[i] <= 2 x 10^6, for all i in [0, n-1]
Output Format
- Array is sorted in numSwaps swaps, where numSwaps is the number of swaps that took place.
- First Element: firstElement, where firstElement is the first element in the sorted array.
- Last Element: lastElement, where lastElement is the last element in the sorted array.
