- Python. Please solve quickly!!arrow_forwardModify the recursive Fibonacci function to employ the memoization technique discussed in this chapter. The function creates a dictionary and then defines a nested recursive helper function named memoizedFib. You will need to create a dictionary to cache the sum of the fib function. The base case of the fib function is the same as before. However, before making any recursive calls, the helper function looks up the value for the function’s current argument in the dictionary (use the method get, with None as the default value). If the value exists, the function returns it and skips any recursive calls. Otherwise, after the helper function adds the results of its two recursive calls, it saves the sum in the dictionary with the current argument of the function as the key. Note: The program should output in the following format: n fib(n) 2 1 4 3 8 21 16 987 32 2178309 ---------------------------------------------------------------------------------- def…arrow_forwardin phython language Write a function named getOddList(). The function takes one parameter which is a list(e.g. inputlist). The function will find the odd numbers in the list and return it as a new list. Call the function with a sample list given as an argument, then print the oddlist. Sample output for a sample list [-4,6,4,7,13,78,9]: [7,13,9]arrow_forward
- Question: First write a function mulByDigit :: Int -> BigInt -> BigInt which takes an integer digit and a big integer, and returns the big integer list which is the result of multiplying the big integer with the digit. You should get the following behavior: ghci> mulByDigit 9 [9,9,9,9] [8,9,9,9,1] Your implementation should not be recursive. Now, using mulByDigit, fill in the implementation of bigMul :: BigInt -> BigInt -> BigInt Again, you have to fill in implementations for f , base , args only. Once you are done, you should get the following behavior at the prompt: ghci> bigMul [9,9,9,9] [9,9,9,9] [9,9,9,8,0,0,0,1] ghci> bigMul [9,9,9,9,9] [9,9,9,9,9] [9,9,9,9,8,0,0,0,0,1] ghci> bigMul [4,3,7,2] [1,6,3,2,9] [7,1,3,9,0,3,8,8] ghci> bigMul [9,9,9,9] [0] [] Your implementation should not be recursive.

For example: sumNums [2,3,4,5] returns [2,5,9,14].arrow_forwardI am new to Haskell and I need someone to explain the syntax of this function. The function is supposed to take a single integer parameter. It indicates the maximum value of Fibonacci numbers that will be in the list and it uses recursion to generate the list. fibList n = go n 1 1 where go n f s | (f+s) > n = [] | otherwise = (f+s) : go n s (f+s)arrow_forward
- in #lang schemearrow_forwardImplement a function void printAll(void) to print all the items of the list.arrow_forwardIn C++, write a program that reads in an array of type int. You may assume that there are fewer than 20 entries in the array. The output must be a two-column list. The first column is a list of the distinct array elements and the second column is the count of the number of occurences of each element.arrow_forward
- Write a function count_evens(nums) that takes a list of ints called nums and returns the number of even ints in the given list. Note: the % "mod" operator computes the remainder, e.g. 5 % 2 is 1.arrow_forwardWrite a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…arrow_forwardPp# 2: can you help me solve and understand this practice problem please? This is using the language Haskell. A step by step explanation would be appreciated. Thank you!arrow_forward
