How memory is freed using Boundary tag method in the context of Dynamic memory management?
Boundary Tag Method to free Memory
To delete an arbitrary block from the free list (to join it with a newly freed block) without traversing whole list, the free list must be doubly linked. Therefore each free block must have 2 pointers, next and prev to the next and last free block on the free block. (This is needed when joining a newly freed block with a free block that immediately proceeds in memory).
Q1. Define the following terms: (i) Abstract data type. (ii) Column major ordering for arrays. (iii) Row major ordering for arrays. Q2. Explain the following: (i) A
How To implement stack using two queues , analyze the running time of the stack operations ?
implement multiple stacks ina single dimensional array. write algorithams for various stack operation for them.
An unsorted array is searched through linear search that scans the array elements one by one until the wanted element is found. The cause for sorting an array is that we search
Asymptotic notation Let us describe a few functions in terms of above asymptotic notation. Example: f(n) = 3n 3 + 2n 2 + 4n + 3 = 3n 3 + 2n 2 + O (n), as 4n + 3 is of
Q. Assume that we have separated n elements in to m sorted lists. Explain how to generate a single sorted list of all n elements in time O (n log m )?
important points on asymptotic notation to remember
Tree is dynamic data structures. Trees can expand & contract as the program executes and are implemented via pointers. A tree deallocates memory whereas an element is deleted.
extra key inserted at end of array is called
: Write an algorithm to evaluate a postfix expression. Execute your algorithm using the following postfix expression as your input: a b + c d +*f .
