Algorithms 101: Rotate Array in JavaScript — three solutions

NettetTo rotate an array on k steps we need to move each element on k steps to the right other words each element's index should be incremented on k. k is equal to two, each element's index should be incremented by two. It can be done by two steps, on each step, an index will be incremented by one. It's easy for indexes: 0, 1, 2. NettetA left rotation operation on an array shifts each of the array's elements unit to the left. For example, if left rotations are performed on array , then the array would become .Note that the lowest index item moves to the highest index in a rotation. This is called a circular array..

NettetAn array is a collection of elements of similar data types stored in contiguous memory locations. It is used to store a collection of data. We can access the elements of an array by the index at which the element is stored. Given an integer array of N elements, we have to rotate the array by D places. NettetApproach 2. We note that rotating an Array K times is just placing the first K elements at the end and bringing forward rest of the elements. So we store the first K elements in a temporary array. We then bring the remaining N - K elements at the front by moving each of them K places ahead. Finally we append the initial first K elements at the ...
