Q1: Rewrite the following using a for-loop instead of a while-loop: while (i<20){     cout<

C++ The binary search algorithm given in this chapter is nonrecursive. Write and implement a recursive version of the binary search algorithm. The program should prompt Y / y to continue searching and N / n to discontinue. If an item is found in the list display the following message: x found at position y else: x is not in the list Use the following list of integers when testing your program: 2, 6, 8, 13, 25, 33, 39, 42, 53, 58, 61, 68, 71, 84, 97

#include<bits/stdc++.h>using namespace std;bool isPalindrome(string &s){    int start=0;    int end=s.length()-1;    while(start<=end)    {        if(s[start]!=s[end])        {            return false;                    }        start++;        end--;    }    return true;}int main(){    string s;    cout<<"ENTER STRING:";    getline(cin,s);    int n=s.length();    bool flag=true;    for(int i=1;i<n;i++)    {        string lowerHalf=s.substr(0,i);        string upperHalf=s.substr(i,n-i);      if(isPalindrome(lowerHalf) && isPalindrome(upperHalf))      {          flag=false;          cout<<"String A is:"<<lowerHalf<<"\n";          cout<<"String B is:"<<upperHalf<<"\n";          break;      }    }    if(flag)    {        cout<<"NO\n";    }    return 0;} change to stdio.h string.h

C++ Code:  Write a program that finds word differences between two sentences. The input begins with an integer indicating the number of words in each sentence. The next input line is the first sentence and the following input line is the second sentence. Assume that the two sentences have the same number of words and no more than 20 words each. The program displays word pairs that differ between the two sentences. One pair is displayed per line. Ex: If the input is: 6 Smaller cars get better gas mileage Tiny cars get great fuel economy then the output is: Smaller Tiny better great gas fuel mileage economy Add a function named ReadSentences to read the input sentences into two string vectors. void ReadSentences(vector<string>& sentence1Words, vector<string>& sentence2Words, int wordCount) main() already contains code to read the word count and call ReadSentences(). Complete main() to display differing word pairs.

C++ Nested loops: Print seats.   Given numRows and numColumns, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Ex: numRows = 2 and numColumns = 3 prints:1A 1B 1C 2A 2B 2C #include <iostream>using namespace std; int main() {   int numRows;   int numColumns;   int currentRow;   int currentColumn;   char currentColumnLetter;    cin >> numRows;   cin >> numColumns;    /* Your solution goes here  */    cout << endl;    return 0;}
