Using either pseudocode of C++ code, write a function that takes three parameters and performs a sequential search. The first parameter is an array of integers. The second parameter is an integer representing the size of the array. The third parameter takes the value to be search form. The function should return the subscripts at which the value is found or -1 is the array does not contain the search term. Please dont use vectors and explain each step
3. Write a PYTHON function called midpoint quad.py with signature def midpoint quad (func, a, b, N) #quad = midpoint quad ( func, a, b, N) # comments return quad where func indicates the name of a function, a and b are the lower and upper limits of integration, and N is the number of points, not the number of intervals. Test your midpointquad routine by computing f2rdx = 1. Even if you use only one interval (i.e. N = 2) you should get the exact answer because the midpoint rule integrates linear functions exactly. Use your midpoint routine to estimate the integral of the Runge function, f(x) = 1/(1+x2), over the interval [-5, 5]. The exact answer is 2 arctan (5). Fill in the following table, using scientific notation for the error values so you can see the pattern. Midpoint Result Error N h 11 1.0 101 0.1 1001 0.01 10001 0.001 Estimate the order of accuracy (an integer power of h) by examining the behaviour of the error when h is divided by 10. (In previous problems, we have estimated…
Answer in C++ code please! (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its push_back function to add each unique value to the vector.
C++ Problem #1: Create a blank 10x10 integer array using constants for the row and column Create a function printArray() that will print every row and column of the array Create a function notFound() that searches each element in the array and returns true if the passed number already exists in the array and false if it does not Create a function fillArray() that will fill the 2 dimensional array with unique random numbers from 0 to 100 inclusive. No cells should have the same number. Use the notFound() function in this function. Print the entire array. Request a column number to print and use a sentinal loop to make sure the row number is valid. If not then request a column number again Create a function printIter() that prints only the passed column using iteration Create a function printRecur() that prints only the passed column using recursion Print the requested column using printIter() and printRecur() Sample output: The array is: Row 0: 41, 85, 72, 38, 80, 69, 65,…

Write the following function #input: a numerical vector x #output:the normalized vector, i.e. the vector rescaled into [0,1] # the formula to normalize is (x-min(x))/ (max(x)-min(x)) # you can NOT use the functions min and max # you can use %%, nrow, ncol, and length # you can write multiple functions

Write a C program and perform the following tasks as suggested in each section. Test all the below functions from the main function of the program. (a) Create a function named PrepareData() to create an integer array ARR with randomly generated numbers, ranging from 1 to 16. User input must be taken to fix the array length. (b) Create a function named DeleteSpecific() to delete an element from the array ARR at specified position and perform left-shift after deletion. (c) Create a function named PrintUnique() to print all unique elements in the array ARR. (d) Create a function named CountDuplicate() to count total number of duplicate elements in the array ARR.
Python Suppose scDict maps names to test scores. Print each name/score on a separate line Write a function calcStats that calculates and RETURNS the average, highest, and lowest of the scores. The function should NOT print anything. Ex: scDict ={“Joe”:70, “Bob”:90, “Sue”: 95} Output: Joe 70Bob 90Sue 95Average: 85High Score: 95Low Score: 703. Ask the user to enter a name and a score, and put that entry into the scDict. Ask the user to enter a name to delete and remove that entry Check to see if the dictionary contains a key “Mary” and print “YES” if it does. 6. Print the dictionary, sorted by name
