def Search(Tree, TargetValue):
if (Tree is None):
return None # Search failed
elif (TargetValue = = Tree.Value):
return Tree # Search succeeded
elif (TargetValue < Tree.Value):
return Search(Tree.Left, TargetValue)
# Apply the function Search to see if TargetValue is in the subtree identified by the root's left child pointer, and report the result of that search.
elif (TargetValue > Tree.Value):
return Search(Tree.Right, TargetValue)
# Apply the function Search to see if TargetValue is in the subtree identified by the ‘ right child pointer, and report the result of that search.

- Diccrete Structure.arrow_forward1. Recursion & List processing Write a recursive function flatten that takes a list as an argument and returns the flat version of that list. For example, (flatten '(a (b c) d)) -> (a b c d) (flatten '(((a)) (b (c)) d)-> (a b c d)arrow_forwardRecursive Functions 1. Without looking at the standard prelude, define the following library functions using recursion: o Decide if all logical values in a list are true: and [Bool] -> Bool o Concatenate a list of lists: concat: [[a]] -> [a] o Produce a list with n identical elements: replicate :: Int -> a => [a] o Select the nth element of a list: (!!) [a] -> Int -> a o Decide if a value is an element of a list: elem: Eq a => a => [a] -> Boolarrow_forward
- Data Structures and Algorithms ASAP Create a Cantor Set Recursively using Line in processing line(startX,startY,endX,endY) where the starting point of the line is at coordinates (startX,startY) and the ending point of the line is at coordinates (endX,endY) Remember the top left of the screen is (0,0) and the plus x direction is to the right and the plus Y direction is downward Requirements 1) Each line should follow the following pattern https://en.wikipedia.org/wiki/Cantor_set#/media/File:Cantor_set_binary_tree.svg 2) The number of lines created should be printed into the console by returning the number from recursion like we did in circles Optional 3) Integrate colors (if you call stroke(R,G,B) the line will bearrow_forwardPythonarrow_forwardUnique Answerarrow_forward
- Why 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_forwardDraw flow chart ASAParrow_forwardSuppose you are given two integer values x and y. Construct a recursive algo-rithm that uses any combination of the following operations: addition, subtraction, comparison. Calculate the remainder of x divided by y. Specify a set ofexample values for x and y which will result in at least 3 or more recursive calls,and draw the recursion trace diagram for your example.arrow_forward
