Memory Allocation Strategies
If it is not desirable to move blocks of due storage from one area of memory to another, it must be possible to relocate memory blocks that have been freed dynamically. Every time a request is made for storage, a free area large sufficient to accommodate the size requested must be allocated. The most obvious methods for keeping track of the free blocks are to use linear linked list. Every free block having a field containing the size of the blocks and a field having a pointer to be next free block. A global P for free block points to the 1st free block on this list. There are various methods of selecting the free block to use at when requesting storage.
In this unit, the following four advanced data structures have been practically emphasized. These may be considered as alternative to a height balanced tree, i.e., AVL tree.
If quicksort is so quick, why bother with anything else? If bubble sort is so bad, why even mention it? For that matter, why are there so many sorting algorithms? Your mission (sho
Worst Fit method:- In this method the system always allocate a portion of the largest free block in memory. The philosophy behind this method is that by using small number of a ve
How divide and conquer technique can be applied to binary trees? As the binary tree definition itself separates a binary tree into two smaller structures of the similar type,
Merging two sequence using CREW merge
This notation gives an upper bound for a function to within a constant factor. Given Figure illustrates the plot of f(n) = O(g(n)) depend on big O notation. We write f(n) = O(g(n))
Step 1: Declare array 'k' of size 'n' i.e. k(n) is an array which stores all the keys of a file containing 'n' records Step 2: i←0 Step 3: low←0, high←n-1 Step 4: while (l
