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 :-)

hello there,
the logic i quite simple and such questions are give just to
confuse us.
push the given string in a stack and while popping out
ignore the bracket PAIR which contain
i) a lone variable in between
ii) does not contain any operator before or after the bracket.
for eg. if (a+b)*c is there then bracket must not be ignored.
thanks

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.
