The minimum number of swaps required to sort an array is equal to the number of inversions in the array.
The best sorting algorithm to use for an almost sorted array is Insertion Sort. It is efficient for nearly sorted arrays because it only requires a small number of comparisons and swaps to sort the elements.
The best case scenario for bubble sort in terms of time complexity is O(n), where n represents the number of elements in the array. This occurs when the array is already sorted, and no swaps are needed during the sorting process.
The recurrence for insertion sort helps in analyzing the time complexity of the algorithm by providing a way to track and understand the number of comparisons and swaps that occur during the sorting process. By examining the recurrence relation, we can determine the overall efficiency of the algorithm and predict its performance for different input sizes.
Bubble sort uses the algorithm design technique known as "comparison-based sorting." It repeatedly steps through the list to be sorted, compares adjacent elements, and swaps them if they are in the wrong order. This process is repeated until the list is sorted, making it a straightforward but inefficient sorting method, especially for large datasets. The technique primarily relies on simple comparisons and swaps to achieve the sorted order.
Heap's algorithm efficiently generates all possible permutations of a given set by using a systematic approach that minimizes the number of swaps needed to generate each permutation. It achieves this by recursively swapping elements in the set to create new permutations, ensuring that each permutation is unique and all possible permutations are generated.

The best case complexity of the selection sort algorithm is (O(n^2)). This is because the algorithm always consists of two nested loops: one for selecting each element and another for finding the minimum element from the unsorted portion of the array. Regardless of the initial order of the elements, selection sort will always perform the same number of comparisons and swaps, leading to a quadratic time complexity.

they live in swaps
Heres something i whipped up in a hurry... This uses the Bubble Sort method found (related links) #include <iostream> using namespace std; int main(int argc, const char* argv) { int arraysize = 5; //Unsorted array size int array [] = { 5, 3, 4, 2, 1 }; //The array of numbers itself //Display the unsorted array cout << "Before: {"; for (int c=0; c <= arraysize; c++) { cout << array[c]; if (c != arraysize) { cout << ","; } } cout << "}" << endl; //Acctually sort the array int tmp=0; //Used for swaping values for (int loop=0; loop <= (arraysize - 1); loop++) { for (int c=0; c <= (arraysize - 1); c++) //The sort loop { if (array[c] > array[c + 1]) { //Swaps the two values in the array tmp = array[c]; array[c] = array[c + 1]; array[c + 1] = tmp; //Cleanup tmp = 0; } } } //Display the sorted array cout << "After: {"; for (int c=0; c <= arraysize; c++) { cout << array[c]; if (c != arraysize) { cout << ","; } } cout << "}" << endl; return 0; }
Everything has to be entered. You can write down the number with a little notation to show that a swap has been made.
