- 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 =…2.23 LAB: Ordering pizza A local pizza shop is selling a large pizza for $9.99.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.

Let(x1,y1)and(x2,y2)be the geographical latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: \[ d=\operatorname{radius} \times \arccos \left(\sin \left(x_{1}\right) \times \sin \left(x_{2}\right)+\cos \left(x_{1}\right) \times \cos \left(x_{2}\right) \times \cos \left(y_{1}-y_{2}\right)\right) \] Write a program that prompts the user to enter the latitude and longitode of two points on the earth in degrees and displays its great circle distance. The average radius of the earth is6,371.01 km. Note you need to convert the degrees into radians using the Math, toRadi ans method since the Java trigonometric methods use radians. The latitude and longitude degrees in the formula are for north and west.

- ▼ Part A - The effect of an arithmetic shift on signed numbers Let's look at see what happens to signed numbers during a shift operation. As with most problems with number representations, errors can be intermittent. Sometimes the code will work as expected, and other times it will behave in a manner that seems to be totally arbitrary. Consider the following code fragment that makes use of the fact that shifting a value left by one place multiplies the number by 2. By passing in the number to be multiplied and the power of 2 to multiply it by (for example 4 = 22) the correct answer should be passed back from the function after the results are printed for the user to examine. signed int mult_2_to_n (signed int num, int n) { signed int result; result = num << n; printf("%d multiplied by 2^%d %d\n", num, n, result); return result; } Using a signed number as the manipulated integer may cause an error in some cases. Several approaches may be used to fix the problem. Which solutions below…18 9:Y0 .(: Question :).
