Left Rotation
A left rotation operation on an array of size n shifts each of the array's elements 1 unit to the left. For example, if [1, 2, 3 , 4, 5] left rotations are performed on array [1, 2, 3, 4, 5], then the array would become [3, 4, 5, 1, 2].
Given an array of n integers and a number, d, perform d left rotations on the array. Then print the updated array as a single line of space-separated integers.
Input Format
The first line contains two space-separated integers denoting the respective values of n (the number of integers) and d (the number of left rotations you must perform). The second line contains n space-separated integers describing the respective elements of the array's initial state.
Constraints
- 1 <= n <= 10^5
- 1 <= d <=n
- 1 <= ai <= 10^6
Output Format
Print a single line of space-separated integers denoting the final state of the array after performing left rotations.
Sample Input
5
4
1 2 3 4 5
Sample Output
5 1 2 3 4
Explanation
When we perform left rotations, the array undergoes the following sequence of changes:
[1, 2, 3, 4, 5] -> [2, 3, 4, 5, 1] -> [3, 4, 5, 1, 2] -> [4, 5, 1, 2, 3] -> [5, 1, 2, 3, 4]
Thus, we print the array's final state as a single line of space-separated values, which is 5 1 2 3 4.
