A Fill in the blanks with the correct words. 1. The start and stop symbols are oval in shape. 2. The parallelogram symbol is used for input/output in flowchart. 3. The decision symbol has two outputs for true and false conditions. 4. It is a good practice to write algorithm first and then write the code of a program. 5. A flowchart should flow from top to bottom and from left to right. B Write T for the true statement and F for the false one. Correct the false statement(s). 1. There can be more than one start symbol in a flowchart. ( F - because there can only be one start symbol in a flowchart ) 2. You cannot draw a flowchart in more than one page. ( F - because we can draw a flowchart in more than one page by using the off-page connectors ) 3. The arrow lines show the flow of steps. ( T ) 4. The order of instructions in an algorithm is not important. ( F - the order of instructions in an algorithm is important ) 5. You can use the parallelogram symbol for calculations in a flowc

What is a Linked List? A Linked List is a linear data structure. It is a collection of nodes such that each node points to the next node. The size of a linked list isn't fixed as the nodes can be added or removed as and when required. The nodes are created by allocating space from the heap memory, using the new keyword. A singly linked list is one in which each node is only capable to point to the next node. A doubly linked list is one in which each node is capable of pointing to the previous as well as the next node. Basic Operations in a Linked List (a) Insertion : We can insert a node in a linked list. A node can be inserted at the beginning, or at the end, or anywhere in-between the list. (b) Deletion : We can delete a node in a linked list. Firstly, we search for the node to be deleted. If found, the deletion takes place and the linked list is readjusted. If not found, then the deletion operation is cancelled. (c) Traversal : We can traverse a linked list, meaning that we can

An ISBN (International Standard Book Number) is a ten-digit code which uniquely identifies a book. The first nine digits represent the Group, Publisher and Title of the book and the last digit is used to check whether ISBN is correct or not. Each of the first nine digits of the code can take a value between 0 and 9. Sometimes it is necessary to make the last digit equal to ten; this is done by writing the last digit of the code as X. To verify an ISBN, calculate 10 times the first digit, plus 9 times the second digit, plus 8 times the third and so on until we add 1 time the last digit. If the final number leaves no remainder when divided by 11, the code is a valid ISBN. For example: 1. 0201103311 = 10 × 0 + 9  ×  2 + 8  ×  0 + 7  ×  1 + 6  ×  1 + 5  ×  0 + 4  ×  3 + 3  ×  3 + 2  ×  1 + 1  ×  1 = 55 Since 55 leaves no remainder when divided by 11, hence it is a valid ISBN. 2. 00746254X =  10  ×  0 + 9  ×  0 + 8  ×  7 + 7  ×  4 + 6  ×  6 + 5  ×  2 + 4  ×  5 + 3  ×  4 + 2  ×  2 + 1  ×  1
