Describe the main steps involved in carrying out an insertion sort.
Describe the main steps involved in carrying out an insertion sort.
- Starting with the first item, one item at a time is taken from the remainder of the list and placed in the correct position in the sorted part of the list. 2) This is repeated until there are no more unsorted items in the list.

Abstraction
- Involves focusing on essential elements of a problem, ignoring unnecessary details
- Helps identify key aspects to include in a solution
Decomposition
- Breaking down a complex problem into smaller, simpler sub-problems
- Easier to solve smaller sub-problems compared to the original complex one
Structure Diagrams
- Graphical representation of the problem's structure
- Shows subsections and links between them
Algorithmic Thinking
- Defining a problem as a sequence of steps to be followed systematically
- A method to solve problems
Linear Search
- Starts from the first item in a list
- Checks each item until a match is found or the end of the list is reached
- Useful for unsorted data
- Slow on large lists
Binary Search
- Selects the middle element of the sorted list
- If the target value is greater than the middle value, the search continues in the upper half; otherwise, it continues in the lower half
- Repeated until the target is found or the list becomes empty
- Requires the data to be sorted
Bubble Sort
- Compares adjacent elements and swaps if they are in the wrong order
- Repeats the process until no swaps are needed in a pass
- Simple to implement; inefficient for large lists
Insertion Sort
- Takes an unsorted item and places it in the correct position within the already sorted portion of the list
- Efficient for small lists; less efficient for large lists
- Doesn't require much extra memory
Merge Sort
- Divides the list into smaller sublists until each sublist has only one element
- Repeatedly merges sublists into sorted sublists until a single sorted list is created
- Efficient for large lists; uses more memory than other sorts
Flow Diagrams
- Use symbols to represent program flow, data processing, and input/output
Algorithm
- A set of precise instructions to solve a problem or carry out a task
Trace Tables
- Show how the values of variables change during the execution of an algorithm
- Used to follow the steps of the algorithm
