9.16 LAB: Flip a coin Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. Ex: If the input is: 3 the output is: tails heads tails For reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded. Note: A common student mistake is to create an instance of Random before each call to rand.nextInt(). But seeding should only be done once, at the start of the program, after which rand.nextInt() can be called any number of times. Your program must define and call the following method that randomly picks 0 or 1 and returns "heads" or "tails". Assume the value 0 represents "heads" and 1 represents "tails".public static String headsOrTails(Random rand) import…
6.24 LAB: Convert to binary - functions Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The function integer_to_reverse_binary() should return a string of 1's and 0's representing the integer in binary (in reverse). The function reverse_string() should return a string representing the input string in reverse.def integer_to_reverse_binary(integer_value)def reverse_string(input_string) Use Python, please.
5.28 LAB: Convert to binary - functions Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The IntegerToReverseBinary() function should return a string of 1's and 0's representing the integer in binary (in reverse). The ReverseString() function should return a string representing the input string in reverse. string IntegerToReverseBinary(int integerValue)string ReverseString(string userString)

6.28 LAB: Check if array is sorted Use java Programming Write the inOrder() method, which has an array of integers as a parameter, and returns true if the numbers are sorted (in order from low to high) or false otherwise. The program outputs "In order" if the array is sorted, or "Not in order" if the array is not sorted. Ex: If the array passed to the inOrder() method is [5, 6, 7, 8, 3], then the method returns false and the program outputs: Not in order Ex: If the array passed to the inOrder() method is [5, 6, 7, 8 , 10], then the method returns true and the program outputs: In order public class LabProgram {public static boolean inOrder(int [] nums) {/* Type your code here. */ }public static void main(String[] args) {// Test out-of-order example.int [] nums1 = {5, 6, 7, 8, 3};if(inOrder(nums1)){System.out.println("In order");}else{System.out.println("Not in order");}// Test in-order example.int [] nums2 = {5, 6, 7, 8, 10};if(inOrder(nums2)){System.out.println("In…

8.28 LAB: Check if list is sorted Write the in_order() function, which has a list of integers as a parameter, and returns True if the integers are sorted (in order from low to high) or False otherwise. The program outputs "In order" if the list is sorted, or "Not in order" if the list is not sorted. Ex: If the list passed to the in_order() function is [5, 6, 7, 8, 3], then the function returns False and the program outputs: Not in order Ex: If the list passed to the in_order() function is [5, 6, 7, 8, 10], then the function returns True and the program outputs: In order Note: Use a for loop. DO NOT use sorted() or sort().

5.17 LAB: Output words in a sentence that are at least 4 characters long The starter code reads in user input (assumed to be one or more sentences), and removes the punctuation. Iterate through the list of words and output the words that are more than 3 characters long. Ex: If the input is: Hello, how are you today? the output is: Hello today #provided code import stringuserInput = input() # this creates a mapping which maps each punctuation character to a null string (None)mapping = str.maketrans('', '', string.punctuation) # this removes puncutation from the stringuserInput = userInput.translate(mapping) print('User input without punctuation:', userInput) # split the string into wordswords = userInput.split()print('User input contains the following words: ')print(words)
6.14 Lab: Reversing an Integer. In this problem, your task is to complete the reverseNumber(num) function. The input of the function is an integer number num. The function should return a number where all the digits are reversed from the original number. You can assume that the input will be a non-negative integer. Example 1: If the input is: 123 The output is: 321 Example 2: If the input is: 321 The output is: 123 Example 3: If the input is: 1000 The output is: 1 Brainstorming. Oftentimes, a problem as formulated can be made easier when you change the way the data is represented. In this case, this problem can be solved in a clever way using strings. If you first convert the number into a string, you can then reverse the string and convert the number back to an integer. def reverseNumberUsingString(num): numInStringFormat = str(num) #converts the number into a string reversedNumberInStringFormat = numInStringFormat[::-1] #reverses the string reversedNumber =…
