5.18 C++ Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Ex: If the input is: 5 2 4 6 8 10 the output is: 10,8,6,4,2,
22.2 LAB: Reverse list (Use Python) Complete the reverse_list() function that returns a new string list containing all contents in the parameter but in reverse order. Ex: If the input list is: ['a', 'b', 'c'] then the returned list will be: ['c', 'b', 'a'] Note: Use a for loop. DO NOT use reverse() or reversed().
21.4 LAB: Parsing dates (Use Python) Write a program to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990. Hint: Use string[start:end] to get a substring when parsing the string and extracting the date. Use the split() method to break the input into tokens. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3/1/1990 12/13/2003
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.
Python 7.21 LAB: Elements in a range Write a program that first gets a list of integers from input. That list is followed by two more integers representing lower and upper bounds of a range. Your program should output all integers from the list that are within that range (inclusive of the bounds). Ex: If the input is: 25 51 0 200 33 0 50 the output is: 25 0 33 The bounds are 0-50, so 51 and 200 are out of range and thus not output. For coding simplicity, follow each output integer by a space, even the last one. Do not end with newline.
Exercise 20 the string below comes from an alphabet consisting of only characters A and B. Accordingly, write the full code of the program (Use the given space below the question. If you struggle to fit into the space then upload a file) that prints the permutation list that can be formed with the characters A or B, which can replace the question marks, into a text file. (Hint: give a go to recursion) A?AA?BB?A? The output will be like the list below: ABAABBBBAB ABAABBBBAA ABAABBBAAB ABAABBBAAA ABAAABBBAB ABAAABBBAA ABAAABBAAB ABAAABBAAA AAAABBBBAB AAAABBBBAA AAAABBBAAB AAAABBBAAA AAAAABBBAB AAAAABBBAA AAAAABBAAB AAAAABBAAA
U={A,B,C,D,E,F}, A={A,B,D,E}, B={B,C,E,F}, and C={A,B,C,D} complete the following set operations: 1(A'n B) uC' 2. A n (Bu C;)
22.3 LAB: Remove all even numbers from a list (Use Python) Write the remove_evens() function, which receives a list of integers as a parameter and returns a new list of integers containing only the odd numbers from the original list. The main program outputs values of the returned list. Hint: If the original list has even numbers, then the new list will be smaller in length than the original list and should have no blank elements. Ex: If the list passed to the remove_evens() function is [1, 2, 3, 4, 5, 6, 7, 8, 9], then the function returns and the program output is: [1, 3, 5, 7, 9] Ex: If the list passed to the remove_evens() function is [1, 9, 3], then the function returns and the program output is: [1, 9, 3]
19.4 LAB: Output numbers in reverse Write a program that reads a list of integers, one per line, until an * is read, then outputs those integers in reverse. For simplicity in coding output, follow each integer, including the last one, by a comma. Note: Use a while loop to output the integers. DO NOT use reverse() or reversed(). Ex: If the input is: 2 4 6 8 10 * the output is: 10,8,6,4,2, Use python, please.
5.22 C++ Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey - 1 hi - 2 Mark - 1 hi - 2 mark - 1 Hint: Use two vectors, one vector for the strings and one vector for the frequencies.
