What kind of command and control structure is employed in this case?arrow_forwardWhat is the functionality of base case(s) ? Group of answer choices: Call other base cases Make recursive function call Checks the logical error To complete the recursion What is the functionality of base case(s) ? Group of answer choices: Call other base cases Make recursive function call Checks the logical error To complete the recursion What is the functionality of recursive helper method ? Group of answer choices: Define base cases and recursive cases Extends the original recursive method Makes infinite function calls Make function calls to original recursive method A recursion function can be implemented without pending operations. Group of answer choices: True Falsearrow_forward
- How much more time and memory does it take for a computer to execute a recursive function compared to a non-recursive one?arrow_forwardPalindrome should have a recursive definition.arrow_forwardWhy does dynamic programming provide faster solutions that recursive algorithms solving the same problem? 1.avoids resolving overlapping subproblems 2.dynamic programming uses dynamic memory that is more efficient than stack memory 3.loops are always faster than recursion 4.dynamic uses arrays that are faster than function callsarrow_forward
- What is the overhead associated with the execution of a recursive function, both in terms of the amount of memory space and the amount of time needed by the computer, and how is it represented as a percentage?arrow_forwardIn Python: Which of the following is true about recursive functions? Can make some repetitive problems easier to solve and understand. Require less memory than non-recursive functions Faster to execute than non-recursive functions can only be called from the main functionarrow_forwardHow is the repeated calling of a recursion function controlled? What kind of command and control structure is being utilized in this instance?arrow_forward
- ANSWER SHOULD BE WRITTEN IN JAVA CODE USING RECURSION Problem Statement Given a string as input return true or false depending on whether it satisfies these rules: 1) The string begins with an 'x' 2) Each 'x' is followed by nothing, 'x' or 'yy' 3) Each 'yy' is followed by nothing or 'x'arrow_forwardWhat is the overhead that is associated with the execution of a recursive function, both in terms of the amount of memory space that is required and the amount of time that is occupied by the computer?arrow_forwardThe term "dynamic programming" refers to a mathematical optimisation method that involves breaking down a complex problem into smaller subproblems and solving them recursively.arrow_forward
