Methods are used to implement all assignment, relational and arithmetic operators in some programming languages e.g. Ruby and Racket. O True O False

Define a static recursive method that returns the arabic integer equivalent of a roman numeral given to the method as a string argument. java program

What are some of the key differences between static type checking and dynamic type checking?

Use the pseudocode methods below to answer the questions in C++.    FIRST METHOD: COMMENT  parameters should be integers METHOD largestValue(parameters:  num1, num2) BEGIN           IF(num1 >= num2) THEN result ← num1 ELSE result ← num2           ENDIF END largestValue     SECOND METHOD: COMMENT  parameters should be doubles METHOD largestValue(parameters:  num1, num2) BEGIN           IF(num1 >= num2) THEN result ← num1 ELSE result ← num2           ENDIF           RETURN result END largestValue     THIRD METHOD: COMMENT parameters should be integers METHOD largestValue(parameters:  num1, num2, num3) BEGIN IF(num1 >= num2 AND num1 >= num3) THEN         result ← num1 ELSE IF (num2 >= num3) THEN result ← num2           ELSE result ← num3 ENDIF RETURN result END largestValue   Given the pseudocode methods above and on the previous page, which method corresponds to each of the method calls specified?  What would that method return based on…

Recursive Power MethodWrite a method called powCal that uses recursion to raise a number to a power. The method should accept two arguments: The first argument is the exponent and the second argument is the number to be raised (example” powCal(10,2) means 210). Assume that the exponent is a nonnegative integer. Demonstrate the method in a program called Recursive (This means that you need to write a program that has at least two methods: main and powCal. The powCal method is where you implement the requirements above and the main method is where you make a method call to demonstrate how your powCal method work).

IN RUBY Write a function that returns the distance the snail must travel to the top of the tower given the height and length of each step and the height of the tower. Examples total_distance(0.2, 0.4, 100.0) → 300.0 total_distance(0.3, 0.2, 25.0)→ 41.7 total_distance (0.1, 0.1, 6.0) → 12.0
