Solution
The problem is asking to perform a left rotation operation on an array. A left rotation operation shifts each element of the array one unit to the left. For example, if we have an array [1,2,3,4,5] and we need to perform one left rotation, the array becomes [2,3,4,5,1].
The function rotateLeft takes two parameters: an integer d which represents the number of left rotations to perform, and an array arr which is the

Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become:[4,5,6,7,0,1,2] if it was rotated 4 times.[0,1,2,4,5,6,7] if it was rotated 7 times.Notice that rotating an array [a[0], a[1], a[2], ..., a[n-1]] 1 time results in the array [a[n-1], a[0], a[1], a[2], ..., a[n-2]].Given the sorted rotated array nums of unique elements, return the minimum element of this array.You must write an algorithm that runs in O(log n) time.
Rotate an ArrayA group of students is working on a robotics project where a sensor array needs to be adjusted to avoid obstacles. They need a function to simulate rotating the sensor readings (an array of integers) to the right by a given number of positions.Write a function that rotates an array of integers to the right by a given number of positions.Constraints:NAExample:Input:51 2 3 4 51Output:5 1 2 3 4Explanation:Input:5 --->size of array1 2 3 4 5----->elements in array1 ---> number of shifts to be doneOutput:5 1 2 3 4 ---> array after rotating it by 1 step
public static List<Integer> rotateLeft(int d, List<Integer> arr) { int n = arr.size(); List<Integer> result = new ArrayList<>(n); for (int i = 0; i < n; i++) { int newIndex = (i + n - d) % n; result.add(arr.get(newIndex)); } return result; }}
RotationGiven an array Arr[] of N integers and a positive integer K. The task is to cyclically rotate the arrayclockwise by K.Note: Keep the first position of the array unaltered.Constraints:Constraints1 < N <=100-100 <= Arr[i] <=1001 <=K <=100Input format for testingThe candidate should write the code to accept the inputs separated by a new line.First Input: Accept a single positive integer value for N representing the size of Arr[]Second Input: Accept N number of integer values separated by a new line, as elements of Arr[]Third input: Accept a single positive integer value for K representing the number of rotations.Output format for testingThe output must be N integer numbers separated by a single space character.Additional messages in the output will result in the failure of test cases.Example:Input5 -- Value of N{10, 20, 30, 40, 50} -- Elements ofArr[]2 -- Value of KOutput40 50 10 20 30Explanation:Arr[] = {10, 20, 30, 40, 50} and K = 2 (Two cyclical rotations)After 1st rotation = {10, 50, 20, 30, 40}After 2nd rotation = {10, 40, 50, 20, 30}
