A university uses student numbers consisting of 6 digits plus a check digit in the 7th position. The check digit is found by taking the number formed by the first 6 digits modulo 7. A transposition in this setup is a switch of two adjacent digits - check digit excluded. Which transpositions of a student number (a6,a5,a4,a3,a2,a1,a0) (here written as a vector, with check digit a0) will not be detected by the check digit? Explain your answer in full and show any calculations you do. Hint: Note that the value of any ai in the number is ai×10i and consider the difference between the values of the correct and incorrect numbers modulo 7.
can you please solve the question and make it in the right format so that I can copy and paste it? Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey 1 hi 2 Mark 1 hi 2 mark 1 Hint: Use two vectors, one vector for the strings and one vector for the frequencies. 272772.1571588
Given two arrays A and B of equal size N, the task is to find a vector containing only those elements which belong to exactly one array - either A or B - but not both. That is, if some element x appears in both A and B it should not be included in the output vector. Complete the implementation of "getVector(vector<ll>A, vector<ll>B, int N)" function. Example: Input: 1 3 5 7 1 3 2 4 6 7 8 Output: 3 5 1 3 2 4 6 8 The driver codes are attached in the images below. DO NOT CHANGE THE PROVIDED DRIVER CODES AT ALL, LEAVE THEM EXACTLY THE SAME. ONLY ADD CODE TO THE "getVector(vector<ll>A, vector<ll>B, int N)" FUNCTION
Write a C++ program that reads a list of integers, and outputs the two smallest integers in the list, in ascending order. The input begins with an integer indicating the number of integers that follow. Ex: If the input is 5 10 5 3 21 2, the output is: 2 3 You can assume that the list of integers will have at least 2 values. To achieve the above, first read the integers into a vector. Hint: Make sure to initialize the second smallest and smallest integers properly.

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5 2 4 6 8 10 the output is: 10 8 6 4 2 To achieve the above, first read the integers into an array. Then output the array in reverse. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userList = new int[20]; // List of numElement integers specified by the user int numElements; // Number of integers in user's list// Add more variables as needed numElements = scnr.nextInt(); // Input begins with number of integers that follow/* Type your code here. */}}
You are given an array called source, with length n, and a set of m arrays called target, each also with length n. The arrays contain only positive integers. The arrays are unsorted. For any number x, the smallest number in target[x] is guaranteed to be smaller than target[x+1]. All the numbers in target are unique. The following figure illustrates an example of valid source and target arrays for this case, where n=5 and m=6. source = [14, 13, 15, 11, 12]target[0] = [4, 2, 1, 3, 5]target[1] = [6, 8, 7, 10, 9]target[2] = [14, 15, 12, 11, 13]target[3] = [17, 20, 16, 18, 19]target[4] = [22, 21, 24, 23, 25]target[5] = [30, 29, 28, 27, 26] The smallest number in each array in target is styled with bold. You can quickly see that the smallest number in target[0] is smaller than the smallest number in target[1], the smallest number in target[1] is smaller than the smallest number in target[2], and so on. You can also see that there is no duplicate number within the arrays in target. You are…

Write a function that accepts a number, N, and a vector of numbers, V. The function will return two vectors which will make up any pairs of numbers in the vector that add together to be N. Do this with nested loops so the the inner loop will search the vector for the number N-V(n) == V(m). n and m are indices in the vector of numbers. Example A = [1,2,3,4,5,6, 7] Google(5, A) Return [1,2,3,4] and [4,3,2,1] being the pairs that sum to 5. Notice that each pair appears twice. Try to write code that does not do this.
