Algorithm
Problem Name:
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
