Definition Linked List is a collection of nodes , each node has two parts data(or Info) and address (or pointer part). Data (or Info) part can be of simple type (such as integer, character, float double ) or it can be of complex type like string (char *) or user defined type (using struct). Address / Pointer usually called as next , is used to hold address of next node in the linked list as all these memory locations are scattered and cannot be accessed using index variable l

Q.1) How Counting Sort works? Counting sort maintains a separate array to count occurrences of each element and stores them in another array as per their sorted position which is calculates on the basis of occurrences. For example, if the first element is 12 and if it occurs 5 times in the unsorted collection then first 5 positions in the array will be assigned to 12....and so on. Counting sort needs largest number (key) value in the collection to create counting array. For e

Q.1) Define Stack. Stack is an ordered collection of elements into which new element can be inserted or existing element can be deleted from one end called as the top of the stack. Stack is a Last-in-First-Out (LIFO) or First-In-Last-Out (FILO) structure. Q.2) What are the application of Stack? Q.3) "Stack can be considered as a priority queue.". Comment. Stack can be considered as an Ascending Priority Queue with minimal waiting time before popping an element as it is Last-I

Q.1) What is the process of merge sort? Merge sort takes two unsorted subarray and combine them into single sorted array. Q.2) What is the advantage of merge sort? Merge sort is faster in sorting elements as it avoids Swapping (interchanges). It does not require all elements in memory, hence it is best suitable for virtual memory environment. (refer to quick sort for more on virtual memory) Q.3) What is an efficiency of merge sort? Merge sort requires O(nlogn) comparisons irr
