Problem. Write a function reverseDigit, that takes an integer as a parameter and returns the number with its digits reversed. Sample: the value of reverseDigit(9600) is 69, the value of reverseDigit(2021) is 1202; the value of reverseDigit(-123) is -321

Use Python for this question. Also, could you please comment/explain what each line of code represents in this question.   Write a function piggyBank that accepts a sequence of "coins" and returns counts of the coins and the total value of the bank. the coins will be given by a list of single characters, each one of 'Q','D','N',P' , representing quarter, dime, nickel, penny the function returns a tuple with two items: a dictionary with counts of each denomination. They should always be listed in the order 'Q','D','N',P' the total value in whole cents of the amount in the bank   Output for this question is shown in the attached image

Write a function named product that takes two int parameters and returns the product of those two integers. Here is an example: int n = product(7, 5); // n is 35 We are providing a test framework that, if you wish, you may use with a compiler to test your function. What you will submit as your answer to this problem is only the product function. Do not submit things like the #include lines or a main routine. If we take the code you write in the space below and insert it into the program, the resulting program must build without compilation errors (mere warnings are allowed). You do not need to write comments in the code; we will not look at any comments. Here is the test framework that you may copy and paste into a C++ source file. For your own testing purposes, you might add additional tests in the main routine, although you won't be turning them in, of course. #include <iostream> #include <cassert> using namespace std; // SUBMIT AS YOUR ANSWER ONLY THE CODE BETWEEN THIS…
