Selection Sort and Bubble Sort

Selection Sort:
- Selection Sort is a simple comparison-based sorting algorithm.
- It works by dividing the array into two parts - sorted and unsorted.
- In each iteration, the smallest element from the unsorted part is selected and placed at the beginning of the sorted part.
- This process continues until the entire array is sorted.

Bubble Sort:
- Bubble Sort is another simple comparison-based sorting algorithm.
- It works by repeatedly swapping adjacent elements if they are in the wrong order.
- In each iteration, the largest element in the unsorted part "bubbles up" to its correct position.
- This process continues until the entire array is sorted.

Given Array:
a = {7, 8, 9, 6, 5}

Selection Sort iterations:
- In the first iteration, 5 (the smallest element) is selected and placed at the beginning. The array becomes: {5, 8, 9, 6, 7}
- In the second iteration, 6 (the next smallest element) is selected and placed after 5. The array becomes: {5, 6, 9, 8, 7}
- In the third iteration, 7 is selected and placed after 6. The array becomes: {5, 6, 7, 8, 9}
- In the fourth iteration, 8 is selected and placed after 7. The array remains the same: {5, 6, 7, 8, 9}

Bubble Sort iterations:
- In the first iteration, 7 and 8 are compared. Since 8 is greater, they are swapped. The array becomes: {8, 7, 9, 6, 5}
- In the second iteration, 8 and 9 are compared. Since they are in the correct order, no swap occurs. The array remains the same: {8, 7, 9, 6, 5}
- In the third iteration, 9 and 6 are compared. Since 9 is greater, they are swapped. The array becomes: {8, 7, 6, 9, 5}
- In the fourth iteration, 9 and 5 are compared. Since 9 is greater, they are swapped. The array becomes: {8, 7, 6, 5, 9}

Conclusion:
- The number of iterations in the selection sort is 4, while the number of iterations in the bubble sort is 4.
- Therefore, the correct answer is option 'A', i.e., 4 iterations for selection sort and 4 iterations for bubble sort.
