#program should be wrote in python with comments please. Write a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.

In java, the Arrays class contains a static binarySearch() method that returns …… if element is found.     false     true     (-k–1) where k is the position before which the element should be inserted     The index of the element

Assume an array is defined as int[] nums = {7, 15, 23, 5};. Which of the following would place the values in the array in descending numeric order?   a. Array.Reverse(nums);     b. Array.Reverse(nums); Array.Sort(nums);     c. Array.Sort(nums);     d. Array.Sort(nums); Array.Reverse(nums);

Write a c# program that uses the binary search method to search an array:

Please answer the question in the screenshot. The language used here is Java.

Python Write a function that takes a string argument and returns a dictionary data structure containing the number of times each letter occurs in the string.

def print_main_menu(menu):    """    Given a dictionary with the menu,    prints the keys and values as the    formatted options.    Adds additional prints for decoration    and outputs a question    "What would you like to do?"    """     if __name__ == "__main__":    the_menu = {} # TODO 1: add the options from the instructions    opt = None     while True:        # print_main_menu(...) # TODO 1: uncomment, define the function, and call with the menu as an argument        print("::: Enter an option")        opt = input("> ")         if opt == ...: # TODO 2: make Q or q quit the program            print("Goodbye!\n")            break # exit the main `while` loop        else:            if ...: # TODO 3: check of the character stored in opt is in the_menu dictionary                print(f"You selected option {opt} to > {the_menu[opt]}.")            else:                print(f"WARNING: {opt} is an invalid option.\n")

c language and use int main format please

In Python NO IMPORT PICKLE Please check pictures and fix code. Write a program that keeps names and email addresses in a dictionary as key-value pairs.   This is the Required Output example:   Menu ---------------------------------------- 1. Look up an email address 2. Add a new name and email address 3. Change an existing email address 4. Delete a name and email address 5. Quit the program   Enter your choice: 2 Enter name: John Enter email address: John@yahoo.com That name already exists   Menu ---------------------------------------- 1. Look up an email address 2. Add a new name and email address 3. Change an existing email address 4. Delete a name and email address 5. Quit the program   Enter your choice: 2 Enter name: Jack Enter email address: Jack@yahoo.com Name and address have been added   Menu ---------------------------------------- 1. Look up an email address 2. Add a new name and email address 3. Change an existing email address 4. Delete a name and email address 5.…
