Please help review my code, not sure its working as intended.... its in C! Objective Give practice with Recursion in C.Give practice with Backtracking in C.Give practice with Stacks in C. Input will begin with a line containing 2 integers, n and c (1 ≤ n ≤ 20; 0 ≤ c ≤ n choose 2),representing the number of animal exhibits and the number of constraints. The following c lineswill each contain a constraint description in the form of 3 space separated integers, f, s, and d(1 ≤ f, s ≤ n; f ≠ s; 0 ≤ c ≤ n - 2), representing the index of the first animal, the index of thesecond animal, and the exact number of cages that should be in between those 2 animals.For 7 of the 10 cases each animal will be in at most 1 constraint. Output should contain 1 line. In the event that a solution exists, you should print out n spaceseparated integers representing the animal index given in order from the first cage to the last. Ifthere is no solution the output should be only the phrase “No Solution.” (quotes…

Problem 4 We can use lists of numbers like l to represent a mathematical vector. Recall from math classes that a vector is an object with a magnitude and direction. The magnitude is the sqrt of the sum of the squares (for a vector (x,y) it's the Pythagorean theorem for the magnitude (x^2 + y^2)**(1/2)). For a vector of any other length, the formula generalizes to (l[0]^2 + l[1]^2 + l[2]^2 + ... )**(1/2). For this problem use l from Problem 1 and a for loop to compute the magnitude of l with the result stored in l_mag. For l above, its magnitude is 12.96. Python gives you the ** exponentiation operator to raise a number to a power. You could also import math and use math.sqrt(). l = [1, 2, 3, 4, 5, 7, 8] Please give proper explanation and typed answer only.
In c++, Thanks!!! Write the simplest program that will demonstrate iteration vs recursion using the following guidelines - Write two primary helper functions - one iterative (IsArrayPrimeIter) and one recursive (IsArrayPrimeRecur) - each of which Take an array and its size as input params and return a bool such that 'true' ==> array and all elements are prime, 'false' ==> at least one element in array is not prime, so array is not prime. Print out a message "Entering <function_name>" as the first statement of each function. Perform the code to test whether every element of the array is a Prime number. Print out a message "Leaving <function_name>" as the last statement before returning from the function. Remember - there will be nested loops for the iterative function and there can be no loops at all in the recursive function. You will need to define one other helper function (IsPrimeRecur) for the recursion which should also not contain any loops to make it a…
