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)
1. Write a function that returns a vector. The function will accept names (full names: Given, Middle, & Family name for each) for the vector string to be returned as many as the user will enter. The enter key will just be the data required to end the input process. 2. Write a function that returns a vector with given names. The function will extract the given name from all the elements of the vector specified as parameter. The extracted given names will be assigned to another vector that is to be returned. 3. Write a function with vector as it's parameter. The function will display all elements of the vector specified. 4. Write a program for using all the functions created from number 1 to 3 above.
Code in C. Solve the code below. Write a function that takes a vector of integers, an integer n representing the number of elements in that vector, and an integer b. Implement the sequential search algorithm to look for the integer b in the vector. The sequential search works as follows: you must look at all the elements of the vector until you find the b, from the first to the last. The function must return an integer representing how many elements the function tested until it found b. If it does not find the function, it must return 0. The name of the function must be called "busca_seq". int busca_seq(int vetor[], int n, int b) { //your code } My Code #include<stdio.h> int busca_seq(int vetor[], int n, int b) { int i; for(i = 0; i < n; i++){ if(vetor[i] == b) return (i+1); } { int vet[5],n = 5,b,x; vet[0] = 1; vet[1] = 2; vet[2] = 3; vet[3] = 4; vet[4] = 5; scanf("%d",&b); x = busca_seq(vet,n,b); printf("%d",x); return 0; } }
Function: randOps Input: (1xN double) A Vector of numbers (N>=2 and even) Output: (double) A number Function Description: Given a 1XN vector where N>=2 and even, perform the following random operations in the following order and return the resulting number 1. Extract all even indexed values into a vector and multiply them by 3 2. Extract all odd indexed values into a vector and divide by 5 3. Subtract the results of Step 2 from the results of Step 1. 4. Calculate the product of all the values contained in the vector result of Step 3. 5. Calculate the value needed to get the number from Step 4 to the next highest integer. 6. Round your result from Step 5 to 5 decimal places Hint(s): ▪ prod(), ceil() and round() may be Examples: ans1 = randOps ([2 5 4 1 3 4 2 1]) >>ans1 = 0.9632 ans2 = randOps ([3 6 2 5]) >> ans2 = 0.9600 ans3 = randOps ([30 40 10 20 50 80]) >> ans3 = 0

Finding the Minimum of a Vector Write a function to return the index of the minimum value in a vector, or -1 if the vector doesn't have any elements. In this problem you will implement the IndexOfMinimumElement function in minimum.cc and then call that function from main.cc. You do not need to edit minimum.h. Index of minimum value with std::vector Complete IndexOfMinimumElement in minimum.cc. This function takes a std::vector containing doubles as input and should return the index of the smallest value in the vector, or -1 if there are no elements. Complete main.cc Your main function asks the user how many elements they want, construct a vector, then prompts the user for each element and fills in the vector with values. Your only task in main is to call the IndexOfMinimumElement function declared in minimum.h, and print out the minimum element's index. Here's an example of how this might look: How many elements? 3 Element 0: 7 Element 1: -4 Element 2: 2 The minimum value in your…
Assume you have a non-empty vector vec in your Matlab workspace. Will the following command: >> length(vec(vec == max(vec))) count all elements in vec with values equal to the maximum value in vector vec? Yes No
MATLAB: Create a vector named n which starts at -10 and steps by 1 to end at +10 by using the start:step:stop syntax. Next, generate a vector x1 so that x1 satisfies the mathematical relationship ?ଵ[?]=(0.60). Since n is a vector, one will need to utilize 0.60.^n (i.e., .^ is used in place of ^) to define x1. Redo the work just completed, but for a vector x2 where x2 satisfies the mathematical relationship ?ଶ[?]=(0.85). Repeat the work just completed, but for a vector x3 where x3 satisfies the mathematical relationship ?ଷ[?]=(1.10). In one figure window, plot x1 as a function of n using the stem command. The stem plot must show BLACK (versus the default blue) lines that have filled circles and a line width of 2; refer to the lecture example script file. Further, the horizontal axis label (xlabel) must be n, the title (title) must include your name and the vertical axis label (ylabel) must show ?ଵ[?]=(0.60)(note the subscript and superscript). In addition, turn on the grid (doc grid),…
Question : Imagine that you track your commute times for (10 days) and recorded your observations in minutes as {17, 16, 20, 24, 22, 15, 21, 15, 17, 22}. Enter your observations into a series (vector) in Python and label it 'data'. Next answer the following questions: ● How many times were your commute 20 minutes or more? Hint: Write a condition!
