Java Program to left rotate the Array
The following Java program rotates the array to d rotational integer. A 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 [1,2,3,4,5], then the array would become [3,4,5,1,2]. The Code makes use of swapping using temp variable for circular rotation from left to right…

Finding Kth Maximum Number from an Array in Java
The following program is used to find the Kth Maximum number from a given unsorted array. The approach on which this code is written uses sorting and then gives out the Kth maximum number. This can be done without sorting too. At the end of the code, you will get a sorted array and hence it…
