6) While there is a built-in pop_back() method for vectors, there is no built-in pop_front method. Suppose a program needs a pop_front() method that will remove the first element from the vector. For example if the original vector is [1, 2, 3, 4, 5], then after passing in this vector to pop_front() the new resulting vector will be [2, 3, 4, 5]. Which of the options below is the correct implementation of pop_front()? Group of answer choices D-) void pop_front(vector<int> &v){ for(int i=0; i<(v.size()-1); i++)v[i+1] = v[i]; v.pop_back(); } C-) void pop_front(vector<int> &v){ for(int i=0; i<(v.size()-1); i++)v[i] = v[i+1]; v.pop_back(); } B-) void pop_front(vector<int> &v){ for(int i=0; i<v.size(); i++)v[i+1] = v[i]; v.pop_back(); } A-) void pop_front(vector<int> &v){ for(int i=0; i<v.size(); i++)v[i] = v[i+1]; v.pop_back(); } 7) Suppose a program has the following vector: [99, 23, 55, 71, 87, 64, 35, 42] The goal is to…
I need to create a function that replicates Python's filter function # This method creates a new Dynamic Array, where the value of each element is derived by # applying a given map_func to the corresponding value from the original array. # It works similarly to the built-in Python map() function. def map(self, map_func) -> object: """ Create new array where each value is mapped to original array value """ ...

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", "*"}.
Please add proper comments in the code given below. int maxSubArray(vector<int>& nums) { int csum=0,maxsum=INT_MIN; for(int i=0;i<nums.size();i++) { csum+=nums[i]; if(csum>maxsum)maxsum=csum; if(csum<0)csum=0; } return maxsum; }
Consider the following code snippet: vector num (3) ; num [0] = 1; num [1] = 2; num [2] = 3; num.pop_back(); Which element or elements of the vector are removed by the pop_back() function in the given code snippet? The element with index 0 The element with index 1 The element with index 2 All the elements
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…

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),…
