## Algorithm

Problem Name: C++ Class Template Specialization

In this HackerRank Functions in C++ programming problem solution,

You are given a main function which reads the enumeration values for two different types as input, then prints out the corresponding enumeration names. Write a class template that can provide the names of the enumeration values for both types. If the enumeration value is not valid, then print unknown.

Input Format

The first line contains

, the number of test cases.
Each of the subsequent lines contains two space-separated integers. The first integer is a color value, , and the second integer is a fruit value f.

Constraints

• 1 <= t <= 100
• -2 * 10*9 <= c <= 2 * 10**9
• -2 * 10*9 <= f <= 2 * 10**9

Output Format

The locked stub code in your editor prints t lines containing the color name and the fruit name corresponding to the input enumeration index.

Sample Input

2
1 0
3 3


Sample Output

green apple
unknown unknown
