Left rotate array by k

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. NettetWe are given with an integer array and value of k, and need to print the array after cyclically rotate it by k positions. Method Discussed : Method 1 : Using Temporary Array. Method 2 : By rotating elements one by one. Method 3 : By Using the reversing Concept. Method 3 : Using juggling algorithm

We can directly put an array element to its respective position. # Input 1,2,3,4,5,6,7 k=3 #Output [5,6,7,1,2,3,4] Example for index-0, we need to copy it to index-0 + k index. For later index, this value might exceeds the length of array. For that, we can take a mod of length.

Nettet13. jun. 2024 · Given an array, rotate the array to the right by k steps, where k is non-negative. Example 1: Input: [1,2,3,4,5,6,7] and k = 3 Output: [5,6,7,1,2,3,4] And here is my solution: func rotate (nums []int, k int) { k = k % len (nums) nums = append (nums [k:],nums [0:k]...) fmt.Println (nums) } It is a straight forward algorithm but it does not work. 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.
