Hacker Rank solution For Day 19: Interfaces

Problem:- Write a Hackerrank Solution For Day 19: Interfaces or Hacker Rank Solution Program In C++ For " Day 19: Interfaces " or Hackerrank 30 days of code Java Solution:Day 19: Interfaces solution or Hackerrank solution for 30 Days of Code Challenges or Hackerrank 30 days of code Java Solution, Day 19: Interfaces solution, or C/C++ Logic & Problem Solving: Day 19: Interfaces or Hacker Rank Solution For Day 19: Interfaces.

Check This:- Hacker rank solution for Strings, Classes, STL, Inheritance in C++.

Explanation:- This is a very simple problem(Interfaces) we have to just calculate divisor sum and print the sum of the divisor. we can do this by run the loop(started with 1 and end with N) and put the condition if number N is divided by I(where I = 1 to N) than the sum of the divisor is added each time when if N%I==0. Let's take an example and try to understand the problem step by step.

Example:- Let's assume Number N is 24 and we have to calculate the Divisor sum so we divide the number by I=1 to I=24 with the help of "For Loop" Take a look at step by step.

Step 1: If(N % I ==0) then Sum or total is Sum = Sum + I Or Total = Total + I.

Step 2: Print the total outside the "For Loop". Here Divisor of 24 = 1 + 2 + 3 + 4 + 6 + 8 + 12 + 24 = 60.
