3 boys go to the restaurant. Their bill was 75 rs..
So they contributed 25 each. Manager then gives 5 rs back
to the waiter and then waiter gave 3 rs back to them and
put 2 rs into his pocket..
So their actual contribution is 24 because they got 1-1 rs
back. so 24*3=72 and 2 rs into the waiter's pocket. so
74+2=74
where is 1 rs?
In a college, the science department has three disciplines.

both chemistry and physics, 138 students study both physics
and biology, 152 students study both chemistry and biology.
73 students study all three disciplines. Can you determine
how many students there are in the science department?

Given a sequence of integers, there are a few sequences
which result in balanced
binary search trees i.e., AVL trees. Write a program that
takes a sequence of integers
as input and outputs the number of such sequences that
result in the balanced binary
search trees.
Input Format:
Single line contains sequence of integers terminated by -1.
Output format:
Print the number of AVL tree possible from that input sequence.
Sample Input:
1 2 3 -1
Sample Output:
2
Given an N × N array of positive and negative integers, find
the sub-rectangle with
the largest sum. The sum of a rectangle is the sum of all
the elements in that rectangle.
In this problem the sub-rectangle with the largest sum is
referred to as the maximal
sub-rectangle. A sub-rectangle is any contiguous sub-array
of size 1 × 1 or greater
located within the whole array.
Input Format:
First line contains the size of matrix.
Followed by n lines and each line contain n integers
separated by space.
Output format:
Single integer which represents maximum sum of rectangle.
Sample Input:
4
0 -2 -7 0
9 2 -6 2
-4 1 -4 1
-1 8 0 -2
Sample Output:
15
