Q4 (Intro to R+ If statements + Functions) Q4: Create a function 'strictly_increase' that takes a vector with length of 3, and checks if the elements of the vector are strictly increasing. If so, return True. Otherwise, return False. e.g., strictly_increase(c(1,2,3)) TRUE strictly_increase(c(1,2,1)) e.g., FALSE

Part 2: Unroll Write a function called unroll, which takes in a square array of arrays (i.e. a grid with n rows and n columns). An input could look like this: const square = [ [1, 2, 3, 4], [5, 6, 7, 8], ]; [9, 10, 11, 12], [13, 14, 15, 16] unroll should take in such a square array and return a single array containing the values in the square. You should obtain the values by traversing the square in a spiral: from the top- left corner, move all the way to the right, then all the way down, then all the way to the left, then all the way up, and repeat. For the above example, unroll should return [1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5, 6, 7, 11, 10].
I/ implement copyToVec such that: // 1) receives three parameters, an array, the array's size, and a vector // 2) copy elements from the array to the vector. Copy elements from 0 to size-1 // 3) using the RANGE-BASED for Loop ONLY, add 0.9 to every element in the vector /* implement main such that: 1) crate an array of size 100 and type float 2) prompt the user to enter 50 values 3) create a new instance of type vector that can store float values 4) invoke copyVec using this exact statement: copyToVec(arrFloat, 30, vecFloat); 5) Using the RANGE-BASED for Loop. print the values from the vector such that that the output is formatted as shown below. Use the following input test data: 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 vecFloat[0] vecFloat[1] = 1.290e+01 vecFloat[2] vecFloat[3] vecFloat[4] vecFloat[5] = 1.690e+01 vecFloat[6] = 1.790e+01 vecFloat[7] vecFloat[8] = 1.990e+01…
C++ Do the following lab by an array(not vector) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Find the maximum and minimum grades for each student. Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98

] ] has_perfect You are to write a function has "perfect (graph)" that takes in a BIPARTITE graph as its input, and then determintes whether or not the graph has a perfect matching. In other words, it will return the Boolean value True if it has one, and False if it does not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (has perfect({"A" : ["B", "C"], "B" : ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]}), has perfect ( {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E": ["B","C","F"], "F":["E"]})) This should return True False Python Python
C++ 1. Create a vector of 100 randomly generated integers. Use the count_if function and a lambda function to count the number of even numbers in the vector.2. Repeat Problem 1 for odd numbers.3. Write a function object that prints a number if it is less than 35. Use the function object with the for_each function to display the numbers greater than 50 created in one of the vectors from the problems above.
1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
C++ Sort a vector Define a function named SortVector that takes a vector of integers as a parameter. Function SortVector() modifies the vector parameter by sorting the elements in descending order (highest to lowest). Then write a main program that reads a list of integers from input, stores the integers in a vector, calls SortVector(), and outputs the sorted vector. The first input integer indicates how many numbers are in the list. Ex: If the input is: 5 10 4 39 12 2 the output is: 39,12,10,4,2, For coding simplicity, follow every output value by a comma, including the last one. Your program must define and call the following function:void SortVector(vector<int>& myVec) #include <iostream>#include <vector>using namespace std; /* Define your function here */ int main() { /* Type your code here */ return 0;} Enter program input - 5 10 4 39 12 2
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.
# dates and times with lubridateinstall.packages("nycflights13") library(tidyverse)library(lubridate)library(nycflights13) Qustion: Create a function called date_quarter that accepts any vector of dates as its input and then returns the corresponding quarter for each date Examples: “2019-01-01” should return “Q1” “2011-05-23” should return “Q2” “1978-09-30” should return “Q3” Etc. Use the flight's data set from the nycflights13 package to test your function by creating a new column called quarter using mutate()
