[Question] Rotate array Left K times and Right K times.

[hrj-star]

Problem : Given an array , return its left rotated and right rotated array by K positions.

Sample Input : arr [] =1 2 3 4 5 , K = 5

Output :
Left Rotated array by K=5 times : 1 2 3 4 5
Right Rotated array by K =5 times : 1 2 3 4 5

Sample Input : arr [] =1 2 3 4 5 , K = 4

Left Rotated array by K=4 times : 5 1 2 3 4
Right Rotated array by K =4 times : 2 3 4 5 1

Will implement in Java.

Can you assign it to me for Java?

Can you assign it to me for C++?

Are you sure that's the expected output in that case? To me it looks like it would remain the same in that case, since k equals the length of the array.

Input:
array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
k = 4

Output:
Left-rotated array K(4) times: [4, 5, 6, 7, 8, 9, 0, 1, 2, 3]
Right-rotated array K(4) times: [6, 7, 8, 9, 0, 1, 2, 3, 4, 5]

I will do this in Python.

Yes , there was a typo mistake , the output was for K=4 , have updated , many thanks !
