def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.
Exercise Objectives Problem Description Write a program that reads a string and mirrors it around the middle character. Examples: abcd becomes cdab. abcde becomes deCab AhmadAlami becomes AlamiAhmad Page 1 of 2 Your program must: • Implement function void reflect (char* str) which receives a string (array of characters) and mirrors it. This function does not print anything. • Read from the user (in main()) a string and then print the string after calling function reflect(). • Use pointers and pointer arithmetic only. The use of array notation and/or functions from the string.h library is not allowed.

Q3: Write a complete C++ code for creating an array accepts any 10-integer numbers from the user and then apply the following tasks: 1. Print the smallest index of the smallest element. 2. Print the multiplication of all elements in the array. 3. Put the even & the odd elements of the array in two separate arrays, and then print them.

Q3 / Write a program in C # that lets the user to define the number of rows and columns. Then, the program reads the matrix and finds the index of the even and odd numbers and display them with their corresponding indices. Use adequate messages during the program execution.
C++ Lexicographical Sorting Given a file of unsorted words with mixed case: read the entries in the file and sort those words lexicographically. The program should then prompt the user for an index, and display the word at that index. Since you must store the entire list in an array, you will need to know the length. The "List of 1000 Mixed Case Words" contains 1000 words. You are guaranteed that the words in the array are unique, so you don't have to worry about the order of, say, "bat" and "Bat." For example, if the array contains ten words and the contents are cat Rat bat Mat SAT Vat Hat pat TAT eat after sorting, the word at index 6 is Rat You are encouraged to use this data to test your program.
