in python create a function that raises a keyerror if the key is duplicated

C++ programming!!!! Abstract You are given a file containing many words. Read in all of the words from the file and insert each word into a searchable ADT. Give the user a looping menu allowing them to search for words in the word list. Searches must be be found in O(1) or constant time. Your code must time the search operations, and display the time to the user. For this assignment, you may use the provided word list or another word list with more than 150,000 words. Include this file with your submission. You must design and implement the following classes: Word: This class holds a single word as a string. Basic getters and setters are required. HashTable: This class represents the hash table for storing many words. Main: This is the driver class. The driver: Create a Hash Table Read in all of the words from a text file into the Hash Table Provide a looping menu for the user to perform searches. Time all searches and display the execution time to the user For each...

16. NULL can be assigned to a void pointer. True O False

In C++Using the code provided belowDo the Following: Modify the Insert Tool Function to ask the user if they want to expand the tool holder to accommodate additional tools Add the code to the insert tool function to increase the capacity of the toolbox (Dynamic Array) USE THE FOLLOWING CODE and MODIFY IT: #define _SECURE_SCL_DEPRECATE 0 #include <iostream> #include <string> #include <cstdlib> using namespace std; class GChar { public: static const int DEFAULT_CAPACITY = 5; //constructor GChar(string name = "john", int capacity = DEFAULT_CAPACITY); //copy constructor GChar(const GChar& source); //Overload Assignment GChar& operator=(const GChar& source); //Destructor ~GChar(); //Insert a New Tool void insert(const std::string& toolName); private: //data members string name; int capacity; int used; string* toolHolder; }; //constructor GChar::GChar(string n, int cap) { name = n; capacity = cap; used = 0; toolHolder = new...

In C++, When an array is passed to a function as a pointer, the function doesn't know the size of the array. List 3 ways to handle this problem.

C++ Coding: ArraysTrue and False Code function definitions for eoNum() and output(): Both eoNum() and output() are recursive functions. output() stores the even/odd value in an array. Store 0 if the element in the data array is even and store 1 if the element in the data array is odd. eoNum() displays all the values in an array to the console.

Describe how to pass an array as a parameter to a function.

A-Language- Python Write a fully functioning program that correctly uses a list, reads, and writes from/to an external file. Megan owns a small neighborhood coffee shop, and she has fifteen employees who work as baristas. All of the employees have the same hourly pay rate. Megan has asked you to design a program that will allow her to enter the number of hours worked by each employee and then display the amounts of all the employees’ gross pay. You determine that the program should perform the following steps: The text that is in the file is stored as one sentence. Incorporate the code that reads the file’s contents and calculates the following: total number of words in the file total average number of words per sentence total number of characters in the file total average number of characters per sentence Use function(s) to accommodate this word and character analysis of the file B For each employee: Get the employee name from the file named employee_names.txt (attached in...

True or false: setInterval() executes a function repeatedly until the interval is cleared by clearInterval() using the ID returned by setInterval(). О а. True O b. False

A series of commands can be used to display a function's return address. Remember that any changes you make to the stack cannot prevent the procedure from returning to its caller.

In Python, grades_dict = {'Wally': [87,96,70], 'Eva': [100,87,90], 'Sam': [94,77,90], 'Katie': [100,81,82], 'Bob': [83, 65, 85]} write your own describe function that produces thesame 8 statistical results, for each one of the columns, that the built-in describe() function does.Note 1: Use the sample standard deviation formula (that is, the denominator is: N-1)Note 2: Your algorithm should work for any number of columns not just for 5Note 3: You can use the np.percentile() for the 25% and 75% percentile as well as the sort()built-in functions
