2. Sum: a recursive function that computes the sum of integers 1, 2, 3, …., n for a given number n.
So Sum(6) should return 1 + 2 + 3 + 4 + 5 + 6 , i.e. 21.sum(n) = n + sum(n-1)

1. Implement a recursive function called firstTwo that returns the sum of the firsttwo digits in a positive number. If there is only one digit, that digit is returned.Note this function is returning an integer, not printing. There should be no use ofcout within your function.Title line: int firstTwo(int n)ex. firstTwo(8325) returns 11ex. cout << firstTwo(428); // prints 62. Implement a function called findMinGap that will return the smallest gap betweenadjacent entries of an integer array. A gap between two numbers is the absolutevalue of their difference. For example, if an array contains the elements {10, 14,-5, -3, 0, 5, 7}, the minimum gap is 2 (between -5 and -3).Title line: int findMinGap(int array[], int length)3. Implement a function called findLargestIndex which returns the index of the rowwith the largest sum.ex. int array[3][6] = {{3, 6, 8, 2, 4, 1}, // sum = 24{2, 4, 5, 1, 3, 4}, // sum = 19{1, 0, 9, 0, 1, 0}}; // sum = 11If the findLargestIndex function was called…

Create a recursive function named sequence that accepts an integer n. This function prints the first n numbers of the Fibonacci Sequence separated by a space in one line
Fibonacci Sequence is a series of numbers in which each number is the sum of the two preceding numbers.
In the main function, write a program that accepts an integer input. Call the sequence function by passing the inputted integer.
Input

Question 02:
Write a recursive function that parses a binary number as a string into a decimal integer.
The function header is:
int binaryToDecimal(const string& binaryString)
Write a test program that prompts the user to enter a binary string and displays its decimal equivalent.

3. A palindrome is a sentence that contains the same sequence of letters read-ing it either forwards or backwards. A classic example is "Able was I, ere
I saw Elba." Write a recursive function that detects whether a string is a palindrome. The basic idea is to check that the first and last letters of the
string are the same letter; if they are, then the entire string is a palindrome if everything between those letters is a palindrome.
There are a couple of special cases to check for. If either the first or last character of the string is not a letter, you can check to see if the rest
of the string is a palindrome with that character removed. Also, when you compare letters, make sure that you do it in a case-insensitive way.
Use your function in a program that prompts a user for a phrase and then tells whether or not it is a palindrome. Here's another classic for
testing: "A man, a plan, a canal, Panama!"

Q1: A positive integer is entered through the keyboard, write a function to display the Fibonacci series upto ‘n’ positive integer
(1) Without using recursion
(2) Using recursion .
Q2: To fully define a variable one needs to mention not only its ‘type’ but also its ‘other properties’. In other words, not only do all variables have a data type, they also contain other properties. Explain the concept that will help us to describe the properties of any variable.

11.11 LAB: Number pattern
Write a recursive function called PrintNumPattern() to output the following number pattern.
Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline.
Ex. If the input is:
12
3
the output is:
12 9 6 3 0 3 6 9 12
main.cpp:
#include
using namespace std;
// TODO: Write recursive PrintNumPattern() function
int main(int argc, char* argv[]) {
int num1;
int num2;
cin >> num1;
cin >> num2;
PrintNumPattern(num1, num2);
return 0;
