Array Right Rotation Algorithm
The Array Right Rotation Algorithm is a technique used to rotate the elements of an array in a clockwise direction by a specified number of positions. This algorithm is particularly useful in various programming and data manipulation tasks, as it helps in rearranging the elements of an array in an efficient manner. The main idea behind this algorithm is to shift each element of the array to its right by one position, and the last element of the array moves to the first position, effectively creating a cyclic rotation. This process is repeated for the desired number of rotations, resulting in an array with elements rotated to the right by the specified number of positions.
There are several ways to implement the Array Right Rotation Algorithm, one common approach involves using a temporary array to store the elements being shifted and then copying them back to the original array after the rotation. Another approach is to reverse the entire array, then reverse the first 'k' elements, where 'k' is the number of positions to rotate, and finally, reverse the remaining elements. This method eliminates the need for additional storage space and reduces the time complexity of the algorithm. Regardless of the implementation used, the Array Right Rotation Algorithm is an essential tool for programmers and developers, providing an efficient way to manipulate data structures and solve complex problems.
#include <iostream>
using namespace std;
int main()
{
int n, k;
cout << "Enter size of array=\t";
cin >> n;
cout << "Enter Number of indices u want to rotate the array to right=\t";
cin >> k;
int a[n];
cout << "Enter elements of array=\t";
for (int i = 0; i < n; i++)
cin >> a[i];
int temp = 0;
for (int i = 0; i < k; i++)
{
temp = a[n - 1];
for (int j = n - 1; j >= 0; j--)
{
if (j == 0)
{
a[j] = temp;
}
else
{
a[j] = a[j - 1];
}
}
}
cout << "Your rotated array is=\t";
for (int i = 0; i < n; i++)
{
cout << a[i] << " ";
}
}
