Array rotation in java | Java DSA series

What does rotation of an array mean? Rotation means shifting the elements of an array either to the left or to the right by a given number of positions (k), while keeping the order of elements. Consider the array: 1, 2, 3, 4, 5 If we rotate this array by 1 in counterclockwise direction (left rotation), the first element moves to the end and all other elements shift one position to the left. The rotated array becomes: 2, 3, 4, 5, 1 If we rotate the same array by 2 in counterclockwise direction, elements shift two positions to the left. The rotated array becomes: 3, 4, 5, 1, 2 When the value of k is positive, it represents counterclockwise (left) rotation. Now consider clockwise rotation. If we rotate the array by -1 (clockwise rotation), the last element moves to the front and all other elements shift one position to the right. The rotated array becomes: 5, 1, 2, 3, 4 If we rotate the array by -2 (clockwise rotation), elements shift two positions to the right. The rotated array becomes: 4, 5, 1, 2, 3 So, in this problem: Positive value of k means counterclockwise (left) rotation. Negative value of k means clockwise (right) rotation. This is a basic array problem and is commonly asked in coding interviews. Now let us see how to solve this problem using the most efficient approach. rotate array by k, rotate array by n positions, left rotate array, right rotate array, rotate array inplace, rotate array leetcode, rotate array leetcode solution, rotate array leetcode java, rotate array java, rotate array in java, java array rotation, java program to rotate array, rotate array by k steps java, rotate array without extra space java, array rotation using reversal algorithm, Java dsa series, Java in hindi, Dsa in java, #aasaanpadhaai #javadsaseries
