(2) True or False: Sometimes there are two or more possible matches for an invocation of a method, but the compiler cannot determine the most specific match. Ambiguous invocation causes a compilation error.

Give an explanation for the answer. Thank you
Edit only the class definition. DO NOT CHANGE the code given under 'main' please.
Steps:
Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1. Support addition, subtraction, equality operations and the built-in abs function2. Are Iterable i.e., support for loops and star arguments for unpacking into function calls3. Support a string representation that displays the class name and coordinates stored by the instance: i.e. for an object initialized as: Vector(0, 3), the string representation should be ‘Vector(0, 3)’The code given under main tests for each of the program requirements and subsequently uses the turtle module to plot randomly generated points rotated. A screenshot for a sample run of the program is attached.
Template.py:
from math import hypot, pi
from random import uniform
import turtle as t

if __name__ == '__main__':
# Test Vector class
a, b = Vector2D(0, 3), Vector2D(0, -3)

Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not.

A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - delimeter - Returns: String with characters…arrow_forward
