WebJul 18, 2024 · Rotation of the array means that each element is shifted right by one index, and the last element of the array is also moved to the first place. For example, the rotation of array A = [3, 8, 9, 7, 6] is [6, 3, 8, 9, 7]. The goal is to rotate array A K times; that is, each element of A will be shifted to the right by K indexes. WebIn this tutorial, we will write a java program to left rotate the elements of an array by a specified number. For example, if an array is: {3, 5, 7, 9, 11} and we are left rotating it by 1 then the resulting array after left rotating would be: {5, 7, 9, 11, 3}.
