Introduction to Microservice Architecture Using SpringBoot - Part 1

QUESTION 1:

 

Input: Given a list of numbers separated with a comma. The numbers 5 and 8 are present in the list. Assume that 8 always comes after 5.

Case 1: num1 -> Add all numbers which do not lie between 5 and 8 in the Input List.
Case 2: num2 -> Numbers formed by concatenating all numbers from 5 to 8 in the list

Output: Sum of num1 and num2
Example: 3,2,6,5,1,4,8,9
Num1: 3+2+6+9 =20
Num2: 5148O/p=5148+20 = 5168

CODE : 

 import java.util.*;  
 public class question1  
 {  
      public static void main(String[] args) {  
            int i=0,j=0,sum=0,sum2=0;  
     Scanner sc= new Scanner(System.in);  
     String str[]= sc.nextLine().split(",");  
     while(i<str.length-1)  
     {  
       if(str[i].matches("5"))  
       break;  
       sum+=Integer.parseInt(str[i]);  
       i++;  
     }  
     while(i<str.length-1)  
     {  
       if(str[i-1].matches("8"))  
       break;  
       sum2=sum2*10;  
       sum2+=Integer.parseInt(str[i]);  
       i++;  
     }  
      while(i<str.length)  
     {  
       sum+=Integer.parseInt(str[i]);  
       i++;  
     }  
     System.out.println(sum2+sum);  
      }  
 }
