For the following programming problems, you need to time a section of code in C++. For example, the following statements time the execution of the function doSome thing: #include clock_t start clock(); doSomething (); clock_t finish = clock(); double overal1Time static cast (finish - start) / CLOCKS_PER_SEC;3 1. Consider the following two loops: // Loop A for (i - 1; i <- n; i++) for (j - 1; j - 10000; j++) sum - sum + j; // Loop B for (i - 1; i <- n; i++) for (j = 1; j e n; j++) sum - sum + j; What is the Big O of each loop? Design and implement an experiment to find a value of n for which Loop B is faster than Loop A. 2. Repeat the previous project, but use the following for Loop B: / Loop B for (i - 1; i <- n; i++) for (j - 1; j <- n; j++) for (k - 1; k < j; k++) sum - sum + k:

For the following programming problems, you need to time a section of code in C++. For example, the following statements time the execution of the function doSomething: #include <ctime> clock_t start = clock(); doSomething(); clock_t finish = clock(); double overallTime = static_cast<double>(finish - start)/ CLOCKS_PER_SEC; unsigned long long int sum; Consider the following two loops: //Loop A for(i = 1; i <= n; i++) for(j = 1; j <= 10000; j++) sum = sum + j; //Loop B for(i = 1; i <= n; i++) for(j = 1; j <= n; j++) for(k = 1; k <= j; k++ ) sum = sum + k; What is the Big O of this loop? Design and implement an experiment to find a value of n for which Loop B is faster than Loop A.

In C programming, if the return type of a function is Void how can you implement assert statements? For example, Void ceasar(int n, char*x); //if char = c and n = 3 output == f how do i use assert statements as this does not work assert (caesar(3,c)==f);

In Haskell: Code a function "rangeProduct" that takes two arguments. The function should return 0 if the second argument is smaller than the first, otherwise it should return the product of the range between two numbers, ex: rangeProduct 3 5 --> 60 (because 3*4*5 = 60) What to do for negative numbers to do (if anything) is up to you. Write the program without recursion first and then write it with recursion.
Hello, I was making a hangman simulation in C++. The code runs, but not fully. Could you identify the error and fix it? #include<iostream>#include<cstring> // for string class functions#include<fstream>#include <cctype>using namespace std; int main(){// define variable to get the response from user "Yes" or "No"string response;// Define index variableint w = 0;// define number of words that need to be guessed by the user assume 4const int WORDS = 4;// loopdo{// we will define the hangman bodyconst char body[] = "o/|\\|\\";// here we define the wordsstring words[WORDS] = {"MACAW", "SADDLE", "TOASTER", "XENOICIDE"};// fetch size or lengthstring xword(words[w].length(),'*');// define iterator to fetch the wordsstring::iterator i, ix = xword.begin();// define number of words to prompt for the userchar letters[26]={"\0"};// Now we define the variables which will be used in the simulationint n =0, xcount = xword.length();bool found = false, solved = false, hung =…
