Question

using C++ language,

Create (fill-in) the following functions:

string rotateString(string to_rotate, int direction, int offset) - Rotate a string in the direction indicated by the number of characters indicated by the offset. If the offset is zero or string is empty return or if the direction is invalid return the original string.

Example 1: string to rotate: xyz123

Direction: Right

Offset: 3

Newstring: 123xyz

Example 2: string to rotate: fizzybeer

Direction: Left

Offset: 5

Newstring: beerfizzy

Explanation / Answer

Function code :

NOTE : please include the following header file "#include <algorithm>

//direction = 1 for LEFT and direction = 0 for Right

Example program :-

#include <iostream>
#include <algorithm> // std::rotate
using namespace std;

string rotateString(string to_rotate,int direction,int offset){
    if(direction == 1){
    rotate(to_rotate.begin(), to_rotate.begin() + offset, to_rotate.end());
    return to_rotate;
    }
    if(direction == 0){
         rotate(to_rotate.begin(), to_rotate.end() - offset, to_rotate.end());
        return to_rotate;
    }
}
int main() {
   string s="feezybeer";
   cout<< rotateString(s,1,5)<<endl;

    s="xyz123";
    cout<<rotateString(s,0,3);
   return 0;
}

Output:

beerfeezy
123xyz
