Task - Exception Handling - More Exceptions

[akash-coded]

More Exceptions

Problem

Objective

The previous challenge #15 taught you to manage exceptional situations by using try and catch blocks. In today's challenge, you're going to practice throwing and propagating an exception.

Task

Write a Calculator class with a single method: int power(int,int). The power method takes two integers n and p, as parameters and returns the integer result of n^p. If either n or p is negative, then the method must throw an exception with the message : n and p should be non-negative.

Note : Do not use an access modifier (e.g.: public) in the declaration for your Calculator class.

Input Format

Input from stdin is handled for you by the locked stub code in your code editor. The first line contains an integer, T, the number of test cases. Each of T subsequent lines describes a test case in 2 space-separated integers denoting n and p, respectively.

Constraints

No Test Case will result in overflow for correctly written code.

Output Format

Output to stdout is handled for you by the locked stub code in your editor. There are T lines of output, where each line contains the result of n^p as calculated by your Calculator class' power method.

Sample Input

4
3 5
2 4
-1 -2
-1 3

Sample Output

243
16
n and p should be non-negative
n and p should be non-negative

Explanation

T = 4

T₀ : 3 and 5 are positive so power returns the result of 3³ which is 243

T₁ : 2 and 4 are positive so power returns the result of 2⁴ which is 16

T₂ : Both inputs, -1 and -2 are negative, so power throws an exception n and p should be non-negative is printed.

T₃ : One of the inputs -1 is negative, so power throws an exception n and p should be non-negative is printed.

Given code

#Write your code here

myCalculator=Calculator()
T=int(input())
for i in range(T):
    n,p = map(int, input().split())
    try:
        ans=myCalculator.power(n,p)
        print(ans)
    except Exception as e:
        print(e)
