Explain about Linear and Nonlinear data structures
sureshds

If the elements/nodes have a single successor and predecessor then the list is said to be linear.Stacks and queues are Linear.Linked lists are linear in terms of accessing and non-linear interms of storage.Trees and graphs are pure non-linear.?

Hierarchical Relationship Between Elements
To represent hierarchical relationship between elements, which data structure is not suitable?a. Dequeb. Priorityc. Treed. All of above
Piyush Verma
- Mar 26th, 2010
Both tree and priority has hierarchical relationship because there is parent child relationship in tree and in priority based higher priority element goes to high level.Dequeue has no hierarchy because traversal is possible in both direction.

Only tree has the notion of parent child relationship, other data structures listed here do not have that.

What is the difference between function templates and function overloading?
prabhuvinoth
- Jun 29th, 2010
Function templates makes the function to performs the same task for different data type.Function overloading makes the function to performs different task for different parameters you are passing.
sureshds
- Dec 26th, 2009
In both cases function name is same.But, during function overloading, the function signature is different. Signature is like type of arguments, number of arguments and orderof arguments.For templates the signature is same and ready to accept any kind of data. There is no restriction on type of data.

Function f(x) is continuous
The function f(x) is continuous in [0,1], such that f(0)=-1, f(1/2)=1 and f(1)=-1, We can conclude that 1. f attains the value zero at least twice in [0,1] 2. f attains the value zero exactly once in [0,1] 3. f is non-zero in [0,1] 4. f attains the value zero exactly twice in [0,1]

Colloquially, "continuous" means that you can graph it without picking up your pencil. What you can't tell is whether f(x) crosses the axis lots, or just twice.If the function were disco...

Another way to look at the solution would be to just draw a mental plot of the given values on x and y axis and it would be easy to see that the graph would cut the x axis twice hence two zero's
