He rotates the array clockwise i.e. after rotation the array A = {6,1,2,3,4,5} and delete the last element that is {5} so A = {6,1,2,3,4}. Again he rotates the array for the second time and deletes the second last element that is {2} so A = {4,6,1,3}, doing t...

Given a sorted array arr[] and a number x, write a function that counts the occurrences of x in arr[]. Expected time complexity is O(Logn) Examples: Input: arr[] = {1, 1, 2, 2, 2, 2, 3,}, x = 2 Output: 4 // x (or 2) occurs 4 times in arr[] Input: arr[] = {...

your array is not sorted. In my subsequent post, I will be writing about other algorithmic problems that can be easily solved using BS even when it is not immediately clear that BS can be used. Thank you for taking the time to read this post. I hope you learned or re...
The Map object is perfect for maps, or associative arrays as we call them in the PHP biz. But what about true, indexed arrays? Well actually, JavaScript has always had a great way to handle these - it's not new! It's the Array object. Well, the Array object isn't new, but it ...
http://www.practice.geeksforgeeks.org/problem-page.php?pid=493 Sorting Elements of an Array by Frequency Given an array of integers, sort the array according to frequency of elements. For example, if the input array is {2, 3, 2, 4, 5, 12, 2, 3, 3, 3, 12}, then modify the ...
Output: -1 // 4 doesn't occur in arr[] Method 1 (Linear Search) Linearly search for x, count the occurrences of x and return the count. Time Complexity: O(n) Method 2 (Use Binary Search) 1) Use Binary search to get index of the first occurrence of x in arr[]. Let the index...
1. get the middle element and create root node N. 2. recursively create a balanced BST from the left half of the array and set its root as N's left node. 3. recursively create a balanced BST from the right half of the array and set its root as N's right node. ...
