89. A worldwide ban on the production of certain ozone-destroying chemicals would provide only an illusion of protection.

C-Dac Sample quesion paper - pattern 3
Answer: 1. What is data structure?
A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data.

2. List out the areas in which data structures are applied extensively?
Compiler Design,
Operating System,
Database Management System,
Statistical analysis package,
Numerical Analysis,
Graphics,
Artificial Intelligence,
Simulation

3. What are the major data structures used in the following areas : RDBMS, Network data model & Hierarchical data model.
RDBMS – Array (i.e. Array of structures)
Network data model – Graph
Hierarchical data model – Trees

4. If you are using C language to implement the heterogeneous linked list, what pointer type will you use?
The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a generic pointer type.

5. Minimum number of queues needed to implement the priority queue?
Two. One queue is used for actual storing of data and another for storing priorities.

6. What is the data structures used to perform recursion?
Stack. Because of its LIFO (Last In First Out) property it remembers its ‘caller’ so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls.
Every recursive function has its equivalent iterative (non-recursive) function. Even when such equivalent iterative procedures are written, explicit stack is to be used.

114. In the closing days of the civil War, President Abraham Lincoln was planning to graciously welcome the defeated confederate states back into the Union. After Lincoln was assassinated, however, the "Radical Republicans" in Congress imposed martial law in the South, creating resentment that caused problems well into this century. Had Lincoln lived, the history of regional conflict in 20th century America would have been considerably different.
All of the following assumptions underline the argument above EXCEPT The imposition of martial law in the South was primarily responsible for the resentment felt in the South Had he lived, lincoln would have treated hte defeated South as he had planned Lincoln would have been able to prevent the Radical Republicans in Congress from imposing martial law in the South Factors other than the imposition of martial law in the South affected the history of regional conflicts in 20th century America


115 A politician wrote the following: "I realize there are shortcomings to the questionaire method. However, since I send a copy of the quetionnaire to every home in the district, I believe the results are quite representative....

116 A worldwide ban on the production of certain ozone-destroying chemicals would provide only an illusion of protection. Quantities of such chemicals, already produced, exist as coolants in millions of refrigerators. When they reach the ozone layer in the atmosphere, their action cannot be halted. So there is no way to prevent these chemicals from damaging the ozone layer further.
Which of the following, if true, most seriously weakens the argument above?
It is impossible to measure with accuracy the quantity of ozone-destroying chemicals that exist as coolants in refrigerators.
In modern societies, refrigeration of food is necessary to prevent unhealthy and potentially life-threatening conditions.
Even if people should give up the use of refrigerators, the coolants already in existing refrigerators are a threat to atmospheric ozone.
The coolants in refrigerators can be fully recovered at the end of the useful life of the refrigerators and reused.
