PYTHON: create a function code(n) that sorts a list of words alphabetically using a RECURSIVE function. tip: a. check if the length of n = 1, if true, return n and stop b. else, if the length of n >= 1, do the ff: c. get the min(x) (least rank word in alphabetical order) d. create a new array from n, where the min is removed. The new array is m. e. return the array composed of the min + code(m).
Complete the function encrypt, which takes an unencrypted, plaintext message called plaintext and encrypts it according to the following algorithm. The function then returns the encrypted ciphertext message. 1. Using a for-loop, swap the character at each even-indexed position with the one to its right. (Examples: abcdefg becomes badcfe; abcdefg becomes badcfeg) You'll have to carefully accomodate for even-lengthed and odd-lengthed strings. 2. Then, using another for-loop, replace every uppercase letter with its lowercase equivalent, and replace every lowercase letter with its uppercase equivalent. 3. (May be combined with the loop in the previous step in the code.) Except for the character o, replace each digit character with 10 minus that digit. (Examples: 2 becomes 8, 9 becomes 1.) Hint: use ord and/or chr and/or str and/or int instead of a 10-way if- statement! Examples: Function Call encrypt('abCDefGHIJKLMnopQ') encrypt('ABCdefGHIjkL') encrypt('0123456789') encrypt('123456789')…

USING C++ Create two arrays of 1000 (try 10,000 too) numbers each. Populate both arrays with random numbers or use a data reading routine to read in one of the numerical data columns. Use the library routine qsort (http://www.cppreference.com/wiki/c/other/qsort) and sort (http://www.cppreference.com/wiki/stl/algorithm/sort) in turn to sort both the arrays. You will need to write a function for doing comparisons. The function is passed to qsort as a function pointer. The library routine qsort will “callback” your function when it needs to compare two items in the array. Use a profiler to time how long it takes to do the sort. Try a few other sort routines and time them. If you have a compiler IDE which provides profiling tools, you might try it out. Otherwise, you may want to use the very sleepy profiler (http://www.codersnotes.com/sleepy/). Run your program and then run the profiler and select your programs process to profile. If the program runs too fast because you have got a fast…

CSE Python LAB: Question 2} You initially start with a binary string S0 which is of length N and has all 0s. You are then given U updates, which keep transforming the string. The i-th update transforms the string Si-1 into Si, and hence after all the U updates you will be left with SU. A single update is of the form (Li, Ri), which means that all the 1s in the range [Li, Ri] (both end points included) should be changed into 0s, and all the 0s in that range should be changed to 1s. You need to find out which among the U+1 binary strings: S0, S1, .., SU, is lexicographically the largest, and print that string. You have to develop a python program that output a single line containing one binary string Sample Input: 10 10 9 10 6 10 9 10 1 8 3 5 3 3 3 4 3 9 4 8 7 7 Sample Output: 1111100011

In C: Write a simple "brute force" decrypter for an autokey cipher. This program: 1. Reads in an array of characters (up to 100) and converts them to their ASCII values. 2. "Decrypts" the array for each modulo value (the spacebar and all letters, 27 total). 3. Determines the modulo value that has the second-most number of the character 'E' in the decrypted array. 4. Prints the "decrypted" array corresponding with the modulo value determined in step 3.
