Data Structures and Algorithms: Topic 15

Topic 15 covers selection, insertion, bubble, and shell sort algorithms.
Basic sorting block: Takes two numbers as input and determines which is smaller.
Sorting algorithm logic: Combines basic blocks to sort a list.
1st Sorting Algorithm (ColumnWiseSorting): Step-by-step sorting using a column-wise approach. Selects the minimum element in each pass.
Algorithm pseudocode: Detailed steps for the column-wise sorting algorithm:
- Iterates from the leftmost element to the second to last element.
- Finds the minimum element from the current element to the rightmost element.
- Swaps the current element with the minimum element.

2nd Sorting Algorithm (RowWiseSorting):

Logic: Inserts the next element into the correct position within the already sorted portion of the list.
Pseudocode steps: Iterates through the unsorted part. Inserts elements in the correct position within the sorted sublist.

3rd Sorting Algorithm (Bubble Sort):

Logic: Repeatedly steps through the list, comparing adjacent elements and swapping them if they are in the wrong order.
Pseudocode steps: Repeatedly steps through the list. Compares adjacent elements. If out of order, swaps them. The process repeats until the list is sorted

4th Sorting Algorithm (Shell Sort):

Logic: An in-place comparison-based sorting algorithm.
Pseudocode Steps: Uses gap values to improve insertion sort and reduces the number of comparisons needed. Increases efficiency in large lists. Decreases gaps in each subsequent pass.

This quiz explores key concepts and advantages of Shell Sort as compared to Bubble Sort and Insertion Sort. Test your knowledge on algorithm complexity, the significance of the 'gap' variable, and performance metrics related to sorting algorithms.
