Q15 6 Points The following statements from a math quiz program generate random operands and operators for an arithmetic expression. import random a = random.randint(0,10) b = random.randint(0, 10) op = problem = solution = +, or # e.g. 1*9 eval (problem) print("What is " + problem + "?") Fill in the two blanks so that the program will randomly generate arithmetic expressions using one of three operators (*+,-) and print questions like: What is 1*9? What is 2+3? What is 2-9? In the program above, the variable op contains the operator ("** for example) and the variable problem contains the arithmetic expression using that operator ('1*9' for example). Q05. (10 points) (Implement the String Builder class) The StringBuilder class is provided in the Java library. Provide your own implementation for the following methods (name the new class MyString Builder1): public MyStringBuilder 1 (String s); public MyStringBuilder1 append(MyStringBuilder1 s); . public MyStringBuilder1 append(int i); public int length(); public char charAt(int index); public MyStringBuilder1 to LowerCase(); public MyStringBuilder1 public String toString(); substring(int begin, int end); Q15 6 Points The following statements from a math quiz program generate random operands and operators for an arithmetic expression. import random a = random.randint(0,10) b = random.randint(0, 10) op = problem = solution = +, or # e.g. 1*9 eval (problem) print("What is " + problem + "?")
