# HackerRank Cats and a Mouse Solution Hello Programmers, In this post, you will know how to solve the HackerRank Cats and a Mouse Solution. This problem is a part of the HackerRank Algorithms Series.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

## HackerRank Cats and a Mouse Solution

Two cats and a mouse are at various positions on a line. You will be given their starting positions. Your task is to determine which cat will reach the mouse first, assuming the mouse does not move and the cats travel at equal speed. If the cats arrive at the same time, the mouse will be allowed to move and it will escape while they fight.

You are given q queries in the form of x, y, and z representing the respective positions for cats A and B, and for mouse C. Complete the function catAndMouse to return the appropriate answer to each query, which will be printed on a new line.

• If cat A catches the mouse first, print `Cat A`.
• If cat B catches the mouse first, print `Cat B`.
• If both cats reach the mouse at the same time, print `Mouse C` as the two cats fight and mouse escapes.

Example

x =2
y = 5
z = 4
The cats are at positions 2 (Cat A) and 5 (Cat B), and the mouse is at position 4. Cat B, at position 5 will arrive first since it is only 1 unit away while the other is 2 units away. Return ‘Cat B’.

Function Description

Complete the catAndMouse function in the editor below.

catAndMouse has the following parameter(s):

• int x: Cat A’s position
• int y: Cat B’s position
• int z: Mouse C’s position

Returns

• string: Either ‘Cat A’, ‘Cat B, or ‘Mouse C’

Input Format

The first line contains a single integer, q, denoting the number of queries.
Each of the q subsequent lines contains three space-separated integers describing the respective values of x (cat A‘s location), y (cat Bs location), and z (mouse C‘s location).

Constraints

• 1 <= q <= 100
• 1 <= xyz <= 100

Sample Input 0

```2
1 2 3
1 3 2
```

Sample Output 0

```Cat B
Mouse C
```

Explanation 0

Query 0: The positions of the cats and mouse are shown below: Cat B will catch the mouse first, so we print `Cat B` on a new line.

Query 1: In this query, cats A and B reach mouse C at the exact same time: Because the mouse escapes, we print `Mouse C` on a new line.
