    #Python Programming

    l=list(map(int,input().split(” “)))
    k=int(input())
    for i in range(k):
    a1=l[-1]
    l.insert(0,a1)
    l[:]=l[:len(l)-1]
    print(l)

    n=int(input(‘enter the size : ‘))
    k=int(input(‘number of rotation : ‘))
    y=int(input(‘index : ‘))
    b=[]
    for i in range(n):
    c=int(input())
    b.append(c)
    print(‘array before rotation :’,b)
    for i in range(k):
    temp=b[0]
    for j in range(n-1):
    b[j]=b[j+1]
    b[n-1]=temp
    print()
    print(‘array after rotation : ‘,b)
    print()
    print(‘number at index :’,b[y])

    Under while loop by mistake k is k-; This not k- but correct as k–;

    public class ArrayShift
    {
    public static void main(String[] args) {
    int k=2;
    int ct=-1;
    int index=0;
    int a[]=new int[]{3,4,5};
    int b[]=new int[a.length];
    while(k>=1){
    for(int i=0;i<a.length;i++){
    ct++;
    if(i==a.length-1){
    b[index]=a[i];
    index++;
    }
    }
    for(int j=0;j<ct;j++){
    b[index]=a[j];
    index++;
    }
    for(int c=0;c<a.length;c++){
    a[c]=b[c];
    }
    k–;
    ct=-1;
    index=0;
    }
    for(int m=0;m<a.length;m++){
    System.out.print(a[m]);
    }
    }
    }
