- 5. A(n) is an indexed data structure, which means you can select its elements in arbitrary order as determined by the subscript value. a. String b. stack c. array d. list 6. A(n) is a data structure that contains a data item and one or more links. a. collection b. node c. iterator d. interface 7. You could create a circular list from a single-linked list by executing the statement. a. tail.next = head b. head.prev next %3D c. tail.head = next d. head.tail prev 8. How much time does an ArrayList add a new element to the beginning of the list if n is the size of the ArrayList? a. O(1) b. O(n) c. O (n²) d. O(log n) 9. How much time does an ArrayList add a new element to the end of the list if n is the size of the ArrayList? a. O(1) b. O(n) c. O (n²) d. O(log n)is a data structure that makes it easy to rearrange data without having to move data in memory:a. arrayb. stack arrayc. linked listd. queue arrayArrays An array is a sequence of data items that are of the same type, that can be indexed, and that are stored contiguously. Typically, an array is called a data structure used to represent a large number of homogeneous values. The elements of an array are accessed by the use of subscripts. Subscripts start from zero and runs until less than the size of the array. Arrays of all types are possible, including multi-dimensional arrays. Strings are just arrays of characters terminated by a special character called the null character. A typical array declaration allocates memory starting from a base address. The array name is in effect a constant pointer to this memory address. a) Write a complete C program that demonstrates usage of a one-dimensional array of integers. The program should declare an array of a specific size first, and then should ask user to specify values to be stored to the array. The program should finally display all values from the array to the screen for checking if…
- Computer Science JAVASCRIPT .xlsx parser I need to write a public class that reads an .xlsx file and returns an array of data in javascript. The array would be all of the data inside of the file. The file itself is going to be inside of a folder(downloadedFIles) inside of my project. So the public class will need to account for that.Please write in C display Pages 10. Write function display Pages to do the following a. Return type void b. Parameter list includes i. Parameter that contains the page number, data type integer (i.e., page)ii. One-dimensional array, data type integer, that stores the page allocations (i.e., allocation) c. Display to the console the page number d. Write a looping construct to iterate through the frames (i.e.. FRAMES) i. Display to the console the memory block assigned based on the following logic 1. If the value stored at the current index of array allocation is -1 (ie., INVALID), output a dash (i.e., *-*) 2. Else, output the allocation at the current index of array allocationwww Using c++ in sfml make an login interface • Has two button one for child and other for parents after clicking on it, it will appear a new page to put a username and password
- createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).SKELETON CODE IS PROVIDED ALONG WITH C AND H FILES. #include <stdio.h> #include <stdlib.h> #include <string.h> #include <stdbool.h> #include "node.h" #include "stack_functions.h" #define NUM_VERTICES 10 /** This function takes a pointer to the adjacency matrix of a Graph and the size of this matrix as arguments and prints the matrix */ void print_graph(int * graph, int size); /** This function takes a pointer to the adjacency matrix of a Graph, the size of this matrix, the source and dest node numbers along with the weight or cost of the edge and fills the adjacency matrix accordingly. */ void add_edge(int * graph, int size, int src, int dst, int cost); /** This function takes a pointer to the adjacency matrix of a graph, the size of this matrix, source and destination vertex numbers as inputs and prints out the path from the source vertex to the destination vertex.

Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix. To print the matrix to the console: print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat])) Example: Matrix: W R I T X H D R L G L K F M V G I S T C W N M N F Expected: W N M N F G I S T C L K F M V H D R L G W R I T X Matrix: L C S P Expected: S P L C Matrix: A D J A Q H J C I Expected: J C I A Q H A D J
