You learned about priority queues recently and are now ready to solve problems using them! So here's one. Suppose you have an integer array A. For each index i, you want to find the product of the largest, second largest and the third largest integer in the range [1,i). Note: Two numbers can be the same value-wise but they should be distinct index-wise. Input: The first line contains an integer N, denoting the number of elements in the array A. The next line contains N space separated integers, each denoting the ith integer of the array A. Output: Print the answer for each index in each line. If there is no second largest or third largest number in the array A upto that index, then print "-1", without the quotes. Constraints: 1 <= N <= 100000 0 <= A[i) <= 1000000 Sample Input 12345

In C programming, how would you convert a string to a number without using atoi?

program Credit Card Validator - Takes in a credit card number from a common credit card vendor (Visa, MasterCard, American Express, Discover) and validates it to make sure that it is a valid number (look into how credit cards use a checksum). please use #include <iostream>

Answer must be in C++   You have been hired by a coffee shop to write a program to validate employee's login passwords. You must ensure that the password meets certain criteria, as follows: The password must be at least five (5) characters long The password must contain at least one uppercase and at least one lowercase letter The password must contain at least one digit The password must contain at least one of the following  ten characters: ? # % & ! @ { } ^ \ Write the program to allow the user to enter a potential password in the main program, then passes this value (in an array) into a function that will verify that it meets the stated criteria. For each criteria that it does not meet, a message MUST be displayed. For example, if the user enters "qry2" then three messages should display, first that it is not five characters long, second that it does not contain an uppercase letter and third that it does not contain one of the special ten cahracters. It does contain a…

Assignment #2 Instructions: Through this programming assignment, the students will learn to do the following: Learn to work with command line options and arguments Gain more experience with Makefiles Gain more experience with Unix Learn to use some of the available math functions available with C Usage: mortgagepmt [-s] -r rate [-d downpayment] price In this assignment, you are asked to perform a mortgage payment calculation. All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program   You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the…
