Write a function get key that takes as input a dictionary with integers as values, and a function. Evaluate the function on the list of values from the dictionary to obtain a value v. Return the key of the dictionary that maps to v. If there's more than one key, break ties at random. If there's no such value in the dictionary, return None.

Modify 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…
Need help with this: Given a word, write a function that will output a dictionary that will give each character of the word and its frequency. Due to its key-value pair format, dictionaries can be used to present some forms of structured data in an easily readable way. This challenge will help you write code to present frequency data for characters in strings. Dictionaries are very good data structures for organizing data in a readable format. Your aim is to write a function called word_counter, which will take in a line of text and output a dictionary with each letter as a key, the value being the frequency of appearance of the letter. Steps Define the function word_counter and have it take a string argument. Iterate through the string and count the occurrences of each character. Output each character as a key in the output dictionary, with the frequency as the value. At the end of your script, call the word_counter function as shown in Snippet 6.46, pass it the string…

Exercise - Collection Functions Using the code below, use the map function to create an array of Int values, whose values are equal to the original integer value, plus 1. Use $0 as you iterate through the values of the array. Print the resulting collection. 5 let testScores = [65, 80, 88, 90, 47] Using the code below, use the filter function to create a new array of String values. The new array should only include Strings longer than four characters. Use $0 as you iterate through the values of the array. Print the resulting collection. Olet schoolSubjects = ["Math" , "Computer Science", "Gym", "English", "Biology"] Using the code below, use the reduce function to subtract all of the values within the array from the starting value 100. Print the resulting value. let damageTaken = [25, 10, 15, 30, 20]

What is the value of the median-of-3 for the following list. [80, 47, 41, 21, 40, 68, 78, 18, 75, 46, 30] Notes: • Your answer should be a single valid, non-negative, literal Python int value. For example, 123 is a valid int literal. • This question is asking about before any partition operation is carried out. • This is not asking for the median-of-3 index. • You can pre-check your answer (to check it's a valid, non-negative, literal int).
