3.6 LAB: Number pattern Write a recursive function called print_num_pattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For coding simplicity, output a space after every integer, including the last. Do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12

5.12 LAB: User-Defined Functions: Adjust list by normalizing CORAL LANGUAGE ONLY PLEASE When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Define a function named getMinimumInt that takes an integer array as a parameter and returns the smallest value. Then write a main program that reads five integers as input, stores the integers in an array, and calls getMinimumInt() with the array as an argument. The main program then outputs the normalized array by subtracting the returned smallest value from all the values in the array. Ex: If the input is: 30 50 10 70 65 function getMinimumInt() returns 10, and the program output is: 20 40 0 60 55 For coding simplicity, follow every output value by a space, even the last one. Your program should define and use a function:Function getMinimumInt(integer array(?) userVals) returns integer minInt…
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 =…
7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. 311 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. The formula for computing the area of a pentagon is Area 3√3 2 -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5' where r is the length from the center of a pentagon to a vertex. Here is a sample run: Enter the length from the center to a vertex: 5.5 Enter The area of the pentagon is 108.61
5.16 LAB: Adjust list by normalizing (JAVA) When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this java program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Assume that the list will always contain fewer than 20 floating-point values. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("%.2f", yourValue); Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65 The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0. For coding simplicity, follow every output value by a…
11.11 LAB: Number pattern Write a recursive function called PrintNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12 main.cpp: #include using namespace std; // TODO: Write recursive PrintNumPattern() function int main(int argc, char* argv[]) { int num1; int num2; cin >> num1; cin >> num2; PrintNumPattern(num1, num2); return 0; }
