Boxes through a Tunnel C - Hacker Rank Solution
Problem
You are transporting some boxes through a tunnel, where each box is a parallelepiped, and is characterized by its length, width and height.
The height of the tunnel 41 feet and the width can be assumed to be infinite. A box can be carried
through the tunnel only if its height is strictly less than the tunnel's
height. Find the volume of each box that can be successfully
transported to the other end of the tunnel.
Note: Boxes cannot be rotated.
Input Format
The first line contains a single integer n, denoting the number of boxes.
n lines follow with three integers on each separated by single spaces - lengthi, widthi and heighti which are length, width and height in feet of the i-th box.
Constraints
- 1<=n<=100
- 1<=lengthi,heighti,widthi<=100
Output Format
Sample Input 0
4 5 5 5 1 2 40 10 5 41 7 2 42
Sample Output 0
125 80
Explanation 0
The first box is really low, only 5 feet tall, so it can pass through the tunnel and its volume is 5 * 5 * 5 = 125
The second box is sufficiently low, its volume is 1 * 2 * 40 = 80
The third box is exactly 41 feet tall, so it cannot pass. The same can be said about the fourth box.
