Every data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problem
please code in python You place a pawn at the top left corner of an n-by-n chess board, labeled (0,0). For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below. For example: Enter a board size: 4 1 0 0 0 1 1 0 0 1 2 1 0 1 3 3 1

Project Description The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. ----------------------------------------------------------------- the code template is as follows ---------------------------------------------- #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number // Function…
This program goes where no program has gone before, exploring new frontiers in C++. The program performs calculations concerning weight on various planets as well as travel time between planets. In main, use vectors to hold planet names, distance from the sun, and the specific gravity on each planet. These are parallel vectors, so that the information at a position in each vector refers to information concerning the same planet. Your program should first declare variables, include your vectors. Display your course header with the program title and a brief introduction using a cout. Load the data into the three vectors. Start a do while loop as your Play loop. Ask for the user’s name, Earth weight, the speed they want to travel and the planet they wish to visit. You will need to provide a menu with the planet names and a way for the user to select the chosen destination. Your interaction with the user should look similar to this: Using the data you have obtained from…
Consider the following code: int main (void) ( std::vector intVector(0); } intVector.pushback(1); intVector.pushback(2); intVector.pushback(3); // Vector of 0 ints a. Draw the memory layout of intVector when the code is finished. b. Where in memory is intVector allocated?
Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency() then returns the number of occurrences of the search word in the vector parameter (case insensitive). Then, write a main program that reads a list of words into a vector, calls function GetWordFrequency() repeatedly, and outputs the words in the vector with their frequencies. The input begins with an integer indicating the number of words that follow. Ex: If the input is: 5 hey Hi Mark hi mark the output is: hey 1 Hi 2 Mark 2 hi 2 mark 2 Hint: Use tolower() to set the first letter of each word to lowercase before comparing. The program must define and use the following function:int GetWordFrequency(vector<string> wordsList, string currWord) write code in c++
Given a function with one vector parameter scores. How should the parameter be defined if scores may by very large and the function will modify the parameter? A) constant, and pass by value B) not constant and pass by value C) not constant and pass by reference D) constant and pass by reference
Write a function in C++ that takes a vector of strings, and converts each to an int and returns the resulting vector. If a string can't be turned to a long, use a 0 in its place. Note: You cannot use loops in your code (no 'for' or 'while' statements).
In C++ please follow the instructions Write two code blocks -- one code block to declare a bag and its companion type-tracking array (both using the STL vector), and another code block to create and declare a Cat object and put it into the bag. Name the arrays and variables as you wish. Use any data type tracking and any designation for cats -- your choices. Assume that struct Cat is already defined and that all required libraries are properly included -- just write the two separate code blocks, separated by one or more blank lines.
C++ Create a function append(v1, v2) that adds a copy of all the elements of vector v1 to the end of vector v2. The arguments are vectors of integers. Write a test driver.
You may use the vector and iostream libraries. You are allowed to use three built-in vector member functions (and no others) but you may not have to use them all. The member functions you are allowed to use are size(), at(), and push_back() Write a function that outputs a vector of doubles with each number in the vector separated by a space then a newline after the entire vector is output. The whole vector output should be preceded by a single line saying "Current Vector Contents:". Write a function that takes a vector a doubles and reverses the order of all the elements of the vector. Write a function that fills a vector of doubles with positive numbers using the standard input stream cin, terminate the input when the user enters any negative number. A single output prompt should precede the initial input stating directions for user. Write a main function that creates an empty vector, calls functions from 2 & 3 and calls your output function before and after each of your calls…
C++.Write a function, named SecondNegative, that takes a const reference to a vector of doubles, it should return an const_iterator to the element in the vector that is the second value that is negative. If no such element exists, have the iterator point to one past the end.
