In the breadth first topological ordering, we first find a vertex that has a predecessor
vertex and place it first in the topological ordering.
A sequential search works efficiently for large lists.
The function copyStack makes a copy of a stack.
The elements of a list are usually in descending order.
The use of a queue structure ensures that the items are processed in the order they are
received.
The algorithm maxi is used to determine the maximum of two values.
Class objects cannot be passed as parameters to functions or returned as function
values.
The derived class can redefine public member functions of a base class.
The name of the header file containing the class vector is vec.h.
As parameters to functions, class objects can be passed only by reference.
The queue operation end returns the last element of the queue.
If you have 1000 items, each requiring 1 word of storage, chaining requires a total of
4000 words of storage.
Dividing a problem into smaller subproblems is called structured design.
Every node in a linked list has two components: one to store the relevant information
and one to store the address.
In black-box testing, you do not know the internal working of the algorithm or function.
If we compare the push function of the stack with the insertFirst function for general
lists, we see that the algorithms to implement these operations are similar.
The link component of each node is a pointer.
With the help of the function make_pair, we can create pairs without explicitly
specifying the type pair.
Assuming deq is a deque object. the expression deq.back() returns the position of the
last element of deq.
The increment operator increments the value of a pointer variable by twice the size of
the memory to which it is pointing.
