- 8.15 (Displaying a Sentence with Its Words Reversed) Write a program that inputs a line of text, tokenizes the line with function strtok and outputs the tokens in reverse order Note:solve the program without using pointers and in c language#17a Simple Statistics (not in textbook) Generate a STL array or vector of 1000 floating point numbers in the range 0 to 1. Compute the mean, median, and standard deviation of these. You may use function objects and lambda expressions, and the STL algorithms for_each, accumulate, and sort. You may not use any of the built-in looping constructs while, do-while or for. Also you may not create and use any ordinary c++ functions. Hint: The following code can be used to populate your random array named arr auto arr_store = [](float& v) { v = rand()/float(RAND_MAX); }; for_each(arr.begin(),arr.end(),arr_store); Warning, You may need to know some details about lambda expressions that are not covered in the textbook. These will be covered in the weekly lecture and in a sample program in Sakai resources. Note: The theoretical value of the standard deviation for large N is sqrt(1.0/12) which about 0.289. You should be getting a value fairly close to this.Problem Statement: Consider an input string PAL of letters ‘P’, ‘A’, and ‘L’. This string, which is given by the user, ends with ‘#’. It should be stored in a table (or array), called PAL_TAB. The number of each of these letters is unknown. We have a function, called SWAP(PAL, i, j), which places the ith letter in the jth entry of string PAL and the jth letter in the ith entry of PAL. Note that SWAP(PAL, i, j) is defined for all integers i and j between 0 and length(PAL) – 1, where length(PAL) is the number of letters of PAL. 1. Using our algorithmic language, write an algorithm, called Sort_PAL, which sorts the letters in the array PAL_TAB in a way that all P’s appear first, followed by all A’s, and followed by all L’s. The algorithm Sort_PAL should have one parameter: The array PAL_TAB. Also, your solution is correct only if the four constraints below are satisfied: - Constraint 1: Each letter (‘A’, ‘L’, or ‘P’) is evaluated only once. - Constraint 2: The function SWAP(PAL, i, j) is…

How to sort array in descending order in using pointers.Use function to print out the original and sorted arrays, Example Input Input size of array: 10 Input array elements: 20, 2, 10, 6, 52, 31, 0, 45, 79, 40 Output Array sorted in descending order: 79 ,52,45,40,31,20,10,6,2,0Please write the answer readable write the Explicit and Recursive function for the sequence(plz use f and f(x)) -7, 1, 13, 29, 4910.25 LAB: Quadratic formula Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50
