Write a function named addStars that accepts as a parameter a reference to a vector of strings, and modifies the vector by placing a "*" element between elements, as well as at the start and end of the vector. For example, if the vector v contains {"the", "quick", "brown", "fox"}, the call of addStars(v); should modify it to store {"*", "the", "*", "quick", "*", "brown", "*", "fox", "*"}.

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…

Transcribed Image Text Q} Code the given problem using python programming language Sereja has an array consisting of n integers a1 < a2 <... < an. Based on this array, he has to answer m queries represented by pairs integers t and d. The answer for a query is the smallest integer i for which there exist some k ( i < k) such that a; + d > a;+1, a; +1 + d2 a;+2, ..., ar – 1 + d> ak, ak <t and ar+1 > t (if it exists).

ASSIGNMENT: Working with Vectors Write a menu-driven program that will allow the user to run any of the following questions. Please put the functions headers in h file and the functions definitions in a .cpp file. 1. Write C++ code for a loop that simultaneously computes both the maximum and minimum element in a given vector. 2. Write a function double scalar_product(vector a, vector b) that computes the scalar product of two vectors. The scalar product of two vectors A[al, a2, a3) and B(bl, b2, b3} is another vector C given by C{c1, c2, c3} where cl = al * b1, c2 = a2 + b2, c3 = a3 + b3. 3. Write a function that computes the alternating sum of all elements in a vector. For example, if alternatingSum() is called with a vector containing 149 16 9 7 4 9 11 then it computes 1-4+9-16+9-7+4-9+11=-2 4. Write a procedure reverse that reverses the sequence of elements in a vector. For example, if reverse is called with a vector containing 1 49 16 9 7 4 9 11 then the vector is changed 11 9 4 7…
