 For loop Hackerrank Solution in C++


Problem-5:-

A for loop is a programming language statement which allows code to be repeatedly executed.

The syntax for this is

for ( <expression_1> ; <expression_2> ; <expression_3> )
    <statement>
  • expression_1 is used for intializing variables which are generally used for controlling terminating flag for the loop.
  • expression_2 is used to check for the terminating condition. If this evaluates to false, then the loop is terminated.
  • expression_3 is generally used to update the flags/variables.

A sample loop will be

for(int i = 0; i < 10; i++) {
    ...
}

Input Format

You will be given two positive integers,  and  (), separated by a newline.

Output Format

For each integer  in the interval  :

  • If , then print the English representation of it in lowercase. That is "one" for , "two" for , and so on.
  • Else if  and it is an even number, then print "even".
  • Else if  and it is an odd number, then print "odd".

Note: 

Sample Input

8
11

Sample Output

eight
nine
even
odd

Solution-

#include <iostream>
#include <cstdio>
using namespace std;

int main() {
    string arr[11] = {"even","one","two","three","four","five",
                      "six","seven","eight","nine","odd"};
    int a,b;
    cin>>a>>b;

    if((a>=1 && a<=9) && (b>=1 && b<=9)){
        for(int n=a; n<=b; n++)
        {
            cout<<arr[n] <<endl;
        }
    }
    else if((a>=1 && a<=9) && (b>9))
    {
        for(int n=a; n<=9; n++){
            cout<<arr[n] <<endl;
        }
        for(int n=10; n<=b; n++){
            if(n%2==0){
                cout<<arr[0] <<endl;
            }
            else{
                cout<<arr[10] <<endl;
            }
        }        
    }
    else{
        for(int n=a; n<=b; n++){
           if(n%2==0){
                cout<<arr[0] <<endl;
            }
            else{
                cout<<arr[10] <<endl;
            } 
        }
    }
    return 0;
}


Explanation:-

In this Question, the idea is you are given two numbers 'a' and 'b' such that a<=b. You then need to test every number from a to b and output either the text version of the variable (if number <=9) or whether the value is even or odd (if number > 9).

So basically when the inputs are 7,11 you need to test every integer from 7 to 11, so you need to test 7,8,9,10,& 11. This leads to the output specified in the "Sample Output" of  "seven, eight, nine, even, odd".

Java Output Formating Hackerrank Solution in Java

By
  Java Output Formating Hackerrank Solution in Java Problem-5:- Java's  System.out.printf  function can be used to print formatted output. The purpose of this exercise is to test your understanding of formatting output using  printf . To get you started, a portion of the solution is provided for you in the editor; you must format and print the input to complete the solution. Input Format Every line of input will contain a  String  followed by an  integer . Each  String  will have a maximum of   alphabetic characters, and each  integer  will be in the inclusive range from   to  . Output Format In each line of output there should be two columns: The first column contains the  String  and is left justified using exactly   characters. The second column contains the  integer , expressed in exactly   digits; if the original input has less than three digits, you must pad your outp...

  W elcome to Java! Hackerrank Solution in Java Problem-1:- Welcome to the world of Java! In this challenge, we practice printing to stdout. The code stubs in your editor declare a  Solution  class and a  main  method. Complete the  main  method by copying the two lines of code below and pasting them inside the body of your  main  method. System . out . println ( "Hello, World." ); System . out . println ( "Hello, Java." ); Input Format There is no input for this challenge. Output Format You must print two lines of output: Print  Hello, World.  on the first line. Print  Hello, Java.  on the second line. Sample Output Hello, World. Hello, Java. Solution:- public   class   Solution   {      public   static   void   main ( String []   args )   {          /* Enter your code here. Print output...
