Consider using a bitmap versus a linked list of free blocks. The disk contains a total of B blocks, F of which are free. A disk address requires d bits. The bitmap uses one bit for each block. The linked list is a data structure maintained in a dedicated portion of the disk. Each list element points to a single free block.
(a) State the condition under which the two methods use the same amount of disk space, assuming that the linked-list method connects all blocks individually.
(b) For d = 16 bits, determine the fraction of the disk that must be free for the above condition to hold.
(c) Repeat the two problems above, assuming that the linked-list method connects groups of adjacent blocks, rather than individual blocks. That means, each list element points to the first of block of a group, and contains a two-byte number indicating how many blocks are in the group. The average size of a group is five blocks.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).

Suppose s, t, and w are strings that have already been created inside main. write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. that is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. if these conditions hold your code should print (the boolean value) true. if not, your code should print false. (strictly means: no ties) example: if s, t, and w are "cat", "hats", and "skies" your code should print true - their lengths are 3-4-5; but if s, t, and w are "cats" "shirt", and "trust", then print false - their lengths are 4-5-5 enter your code in the box below

What is estimated time of arrival (eta)? a device that measures the acceleration (the rate of change of velocity) of an item and is used to track truck speeds or taxi cab speeds a gps technology adventure game that posts the longitude and latitude location for an item on the internet for users to find a north/south measurement of position the time of day of an expected arrival at a certain destination and is typically used for navigation applications
