Mathematical Calculations: Weights

Difficulty:

Easy

Question:

Q 1. Rob is an astronaut. He is sent to Mars. Rob is tasked to bring back stones exclusively present on Mars. 

- Rob has a bag that can hold a weight of M units.
- There are M stones labeled 1 to M on mars. Stone 1 weighs 1 unit, stone 2 weighs 2 and so on.
- There are N stones which are available on Mars and Earth both. 

Find the maximum number of stones Rob can bring from Mars, such that none of them is available on earth.

Note
  • Rob cannot bag the same rock more than once.

Input Format
Input1: M, denoting the size of the bag and the number of different stones present on Mars.
Input2: N, denoting the number of common stones on Earth and Mars.
Input3[ ]: An N element array containing the list of the weights of the common stones.
 
Output Format
Your function should return the maximum unique stones that can be collected.

Sample Input
10
3
1  3  5

Sample Output
2

Explanation
There are 10 stones on mars i.e. 1, 2, …., 10 which weigh 1, 2, ….., 10 respectively.
Of which 3 Stones (1, 3 and 5) are available on Earth.
So the maximum unique stones Rob can bring from Mars is 2, such that the Maximum Size of Bag doesn’t exceed.
(2, 4) (2, 6) (2, 7) (2, 8) (4, 6) and so max. 2
