Algorithm and Problem solving

what is decompose in computer science?

• To combine multiple systems into one
• To ignore a problem and move on
• To make a problem more complex
• To break down a complex problem or system into smaller, more manageable parts.

what is linear search?

• A search algorithm that only checks the first element in the list
• A search algorithm that checks every element in the list until the desired element is found
• A search algorithm that sorts the list before searching
• A search algorithm that uses a binary approach to find the desired element

what is bubble sort?

• A sorting algorithm that repeatedly steps through the list, compares adjacent elements and keep it original

• A sorting algorithm that repeatedly steps through the list, compares in-adjacent elements and swaps them if they are in the wrong order.

• A sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the right order.

• A sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

what is this python code does?
LEN(Data)

• It returns the length of the variable 'Data'.
• It returns the count in 'Data'.

• It returns the character in 'Data'.

• It returns the string in 'Data'.
