Circular Array Rotation

  • pratikgk98 + 1 comment

    The main problem in the code is the order of the for loop used for rotating the elenets in the array. You should store the last element value in some temporary variable..and then use a decreasing counter in the mentioned for loop ..then u can store the value in temporary variable to the first element The error in ur code of overwriting values is eleminated by this code!👍

      why my code gives wrong answers ...? 

      vector <int> circularArrayRotation(vector <int> a, vector <int> m,int n,int k, int q) 
{
        while(k!=0)
        {
            int end=a[n-1];
            for(int i=n-2;i>=0;i--)
            {
                a[i+1]=a[i];
            }
            a[0]=end;
            k--;
        }
        
    return a;
}

        you need to return q not a.

        you are not supposed to print the whole array a but only the elements at positions in queries

          if you try to interchange the value,t then it does not work,
