To traverse the linear linked list in reverse order, we walk the list until we reach the last element. The last element is processed first, then the second last and so on and finally the first element of the list. To implement this we can use either a stack (a last-in-first-out or...
Approximately each 4th record is enteredinto the page directory, represented in the illustration both by bolding thatrecord and by noting its offset in the page directory array represented at thetop of the illustration. The page directory is stored “backwards” inthe page, so is reversed in thi...
Structure of node doubly linked list is a list that contains links to links to next and previous nodes. Doubly linked list allows traversal in both ways typedef struct*node ; { void *data; struct node *next; struct node *prev; } node; Dummy head nodes Eliminates the special ca...
The processing unit 305 operates under the control of stored software having an overall software structure as shown in FIG. 28. A BIOS (trade mark) system and an operating system kernel have overall control of the processing unit 305. An array of module programs provide instructions for enabling...
30. A method for detecting and counting persons traversing an area being monitored comprising: in a time T1, receiving a first array of binary data containing the grayness level existing over a given area; in a time T2, receiving a second array of binary data containing grayness levels exist...
