Questions 8

Answers

1
What is the biggest drawback of recursion?
It's hard to debug
High resource usage
It runs too fast
It lacks a math base
2
What is a recursive function?
A function that runs indefinitely
A function that calls itself
A function that iterates arrays
A function that repeats in a loop
3
What happens in memory during recursion?
Nothing changes
Variables are destroyed
A copy of the function is stored
Errors accumulate
4
Which classic problem uses backtracking?
Breadth-first search
Binary multiplication
Eight queens on a chessboard
Bubble sorting
5
What principle does backtracking use?
Explore all possible options
Choose a random solution
Avoid using functions
Iterate until it stops
6
What best describes the backtracking technique?
Uses only linear structures
Ignores base cases
Solves in reverse order
Tries and goes back if it fails
7
What is the base case in recursion?
The last value in the list
The stack overflow error
The initial function call
When the function stops calling itself
8
What is a benefit of recursion over iteration?
Easier to write and understand
Less memory usage
Greater complexity
Longer code
