In MATLAB: Write a recursive function called ‘vectflip’ that takes a single vector input argument (the function does not need to check the input format) and returns a single vector input argument that contain the input vector elements in reverse order. Note that you need to write a recursive functio instead that flips the first element by calling vect_flip with the original input vector less its firs elemen ttnsment

What is the return value of the function call Comp(4, 5), given the recursive function Comp defined below:     int Comp(int a,  int b)  {            if (a + b <= 6)                  return 3;            else                  return Comp(a-1, b) + Comp(a, b-1);     }

Write a recursive function called Rev takes a string argument (str) and and integerargument(i – the initial string position). Rev prints the str in reverse. You may not useany built-in reverse function or method. You may use string’s length method.

Write a recursive function to see if the first letter matches the last letter, return the middle letters and check until only 0 or 1 letters are left. It returns True or False. Here is the original code that needs to be checked: # Returns the first character of the string str def firstCharacter(str):     return str[:1] # Returns the last character of a string str def lastCharacter(str):     return str[-1:] # Returns the string that results from removing the first #  and last characters from str def middleCharacters(str):     return str[1:-1] def isPalindrome(str):     # base case #1     # base case #2     # recursive case     pass   Python code
