what is the best algorithm to sort out unique words from a
list of more than 10 million words(1 crore+)?
we need the best technique in the terms of execution time.
Performance
Algorithm A performs 10n2 basic operations and algorithm B
performs 300 lg n basic operations. For what value of n does
algorithm B start to show its better performance?
Subsets
Write an algorithm that prints out all the subsets of 3
elements of a set of n elements. The elements of the set are
stored in a list that is the input to the algorithm. (Since
it is a set, you may assume all elements in the list are
distinct.)
Definition of priority queue was given. We have to implement
the priority queue using array of pointers with the
priorities given in the range 1..n.
The array could be accessed using the variable top. The list
corresponding to the array elements contains the items
having the priority as the array index.
Adding an item would require changing the value of top if it
has higher priority than top.
Extracting an item would require deleting the first element
from the corresponding queue.
The following class was given:
class PriorityQueue
{
int *Data[100];
int top;
public:
void put(int item, int priority); // inserts the item with
the given priority.
int get(int priority); // extract the element with the
given priority.
int count(); // returns the total elements in the priority
queue.
int isEmpty(); // check whether the priority queue is empty
or not.
};
We had to implement all these class functions.
Given a table of the form:
Product Sold on
A 1/1/1980
B 1/1/1980
C 1/1/1980
A 1/1/1980
B 1/1/1980
C 2/1/1980
A 2/1/1980
There are 30 products and 10,000 records of such type. Also
the month period during which sales happened is given to u.
Write the program to display the result as:
Product Month No. of copies
A January 12
A February 15
A March 27
B January 54
B February 15
B March 10
C January 37
hello friends, given an expression we have to remove the
unwanted brackets in that expression.
Eg : (a+b) ---> a+b
(a+b)*(c)-----> (a+b)*c. Please mail me if you know
the logic. My mail id is : saravana6m@gmail.com.
Thank you in advance :-)
