Harry loves numbers in the range [m1, m2] (m1 and m2 included). carry decides to gift harry an array of numbers for his birthday. harry wants to find the number of pairs of indices [l, r] for which the sum of all the elements in the range [l, r] lies between m1 and m2.
- Come up with an algorithm with a worst case complexity of O(N2).
- Now improvise this algorithm, assuming all numbers are positive integers.
- What if the numbers could be negative as well? Can you think of an O(nlogn) solution in this case? (Hint: use sorting)
operators, and (2) start thinking about compound entities (like time of day)
that are represented with multiple values.
1. Create a new program called Time.java. From now on, we won’t remind
you to start with a small, working program, but you should.
2. Following the example program in Section 2.4, create variables named
hour, minute, and second. Assign values that are roughly the current
time. Use a 24-hour clock so that at 2:00 PM the value of hour is 14.
3. Make the program calculate and display the number of seconds since
midnight.
4. Calculate and display the number of seconds remaining in the day.
5. Calculate and display the percentage of the day that has passed. You
might run into problems when computing percentages with integers, so
consider using floating-point.
6. Change the values of hour, minute, and second to reflect the current
time. Then write code to compute the elapsed time since you started
Question ) Implement an object oriented ’Character’ class to capture the common attributes and actions of all characters in your game.
Code) Read input from the keyboard to let the user provide values for your character’s attributes of a specific character object (not a superclass object) your code will create.
Code) Since the user could mistype or introduce problems with their typed input, handle all exceptions with exception handling as part of your character data gathering code.
Code) Create a superclass character object, and call its attack method to demonstrate its use
1) Implement an object oriented subclass of Character, to simulate a specific kind of character in your game. For example, a ’warrior’ class. A warrior is a character, but a character is not necessarily a warrior.
2) Include one unique data field for an attribute of the specific character that is not inherited or defined in Character class
3) Implement a method which overrides the Character attack method to make your subclass simulate a more specific kind of attack that relates to its type, with informative printouts
1) Implement an object oriented ’Character’ class to capture the common attributes and actions of all characters in your game. No need to make this class or the subclass public.
2) Declare two data fields for attributes of the character, one textual and one numeric.
3) Implement a constructor method to initialize data fields and set up the character object .
4) Since all characters can attack, implement a method to simulate the character object attacking in some generic way, including informative printouts
Create a Student class with instance variables name, roll, mark and instance methods setStudentDetails(), displayStudent(). One object of the Student class represents a specific student. Create a Singly Linked List in such a way that every node of the Linked List contains 2 parts: stud and link, where, stud stores the reference to a Student object and link stores the reference of the next node. Hence, the Node class (user defined type) has the following structure.
