12.12 LAB: File name change A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is:

11.17 (Bucket Sort) Use Python. Show the whole code input and output when done. A bucket sort begins with a one-dimensional array of positive integers to be sorted and a two-dimensional array of integers with rows indexed from 0 to 9 and columns indexed from 0 to n – 1, where n is the number of values to be sorted. Each row of the two-dimensional array is referred to as a bucket. Write a class named BucketSort containing a function called sort that operates as follows: a) Place each value of the one-dimensional array into a row of the bucket array, based on the value’s “ones” (rightmost) digit. For example, 97 is placed in row 7, 3 is placed in row 3, and 100 is placed in row 0. This procedure is called a distribution pass. b) Loop through the bucket array row by row, and copy the values back to the original array. This procedure is called a gathering pass. The new order of the preceding values in the one-dimensional array is 100, 3 and 97. c) Repeat this process for each subsequent…
3.6.5: Printing array elements separated by commas. Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print:90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline.
task 14.1 in java Follow these steps:● Create a new java file called MyFile.java● Write code to read the content of the text file input.txt. For each line ininput.txt, write a new line in the new text file output.txt that computesthe answer to some operation on a list of numbers.● If the input.txt has the following:Min: 1,2,3,5,6Max: 1,2,3,5,6Avg: 1,2,3,5,6Your program should generate output.txt as follows:The min [1, 2, 3, 5, 6] is 1.The max of [1, 2, 3, 5, 6] is 6.The avg of [1, 2, 3, 5, 6] is 3.4.● Assume that the only operations given in the input file are min, max andavg and that a list of comma-separated integers always follows theoperation. You should define the functions min, max and avg that take ina list of integers and return the min, max or avg of the list.● Your program should handle any combination of operations and anylength of input numbers. You can assume that the list of input numbersare always valid integers and that the list is never empty.● Compile, save and run…
6.28 In Python, Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one. You can assume the original words are unique.

5.23 LAB: Adjust values in a list by normalizing 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 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. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value)) 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. Use Python, please.
13.14 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in ArrayList class (ArrayListLibrary arrayListLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and ArrayListLibrary insertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each insertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D. Salinger the output is: Number of linked list operations: 1 Number of ArrayList operations: 1 Which list do you think will require the most operations? Why?
