5.19 LAB: Word Frequencies  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. Hint: Use two vectors, one for the strings and one vector for the frequencies. Please write in C++

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.

3. String (a) Write a Python function that accepts a string s and an integer n with a single digit (i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) as its arguments, and returns a new string that replaces every digit n found in s by a new digit that equals to (n + 1) %10. The function returns an empty string if n is not a single digit integer or is negative.

If the length of the string is less than 3, your function should print an error message. move_string ("Hello") ->loHel move_string ("Hi, My name is Mark.") -> My name is Mark. Hi, move_string ("Hi")->Invalid String

Q1) A vector is given by x = [7,19,2,14,5,12,4,18,6,13]. Using conditional statements and loops, write a program that creates two vectors from xone (call it N) that contains the number of odd values and their average, and a second (call it T) that contains the number of even values and their median.
