What is a pseudocode and why is it used in programming?

• Pseudocode is an informal description of a computer program or algorithm in a short clear and precise way

• Pseudocode is a programming language widely used in industry

• Pseudocode is only used by beginner programmers

• Pseudocode is a type of code used in video games

How does binary search algorithm work?

• Randomly select elements to compare with the target value

• Sort array and search from the end

• Divide sorted array in half and narrow down search range based on middle element

• Compare every element in array with target value sequentially

Using the linear search I want to search for the number 5 in the list [3, 7, 1, 5, 9]. Which of the following is true for the linear search algorithm?

• In linear search, the algorithm jumps to the middle of the list to find the element

• The algorithm would start at the beginning of the list, compare each element with 5, and stop when it finds the number or reaches the end of the list.

• Linear search is only applicable to strings, not numbers

• Linear search involves sorting the list before searching

Which of the following is NOT a Relational operator in Python?

• ==

• !=

• >>

• <=

Which of these is NOT a logical operators in Python.

• nand

• or

• and

• not

Which of the following is not a conditional statement in Python?

• if statement

• if-else statement

• if-elif staement

• for statement

How can pseudocode help in a program?

• Pseudocode is used to plan and design algorithms before implementing them

• Pseudocode makes the program planning process more complicated.

• Pseudocode is only useful for experienced programmers, not beginners.

• Pseudocode is not necessary as coding directly is more efficient.

Which of the following is true regarding constants?

• Constants can be reassigned to a new value during execution

• Constants are variables whose values can vary

• Constants are used to store data whose values can vary

• Constants are declared and assigned only once and their values remain unchanged

Compare and contrast linear search and binary search algorithms.

• Linear search is only suitable for sorted lists

• Linear search is faster for large lists but harder to implement

• Linear search is simpler but slower for large lists, binary search is faster but requires sorting

• Binary search is slower and doesn't require sorting

Choose the correct examples of relational operators used in Python.

• ===, !, >>, <<

• ==, <>, =>, =<

• ==, !=, >, <, >=, <=

• =, <>, >>, <<
