Any Base To Any Base | aCoding | Day 14

Problem:

1. You are given a number n.
2. You are given a base b1. n is a number on base b.
3. You are given another base b2.
4. You are required to convert the number n of base b1 to a number in base b2.

Input Format

A number n
A base b1
A base b2

Output Format

A number of base b2 equal in value to n of base b1.

Constraints

0 <= n <= 512

2 <= b1 <= 10

2 <= b2 <= 10

Sample Input

111001

2

3

Sample Output

2010

Solution:

import java.util.*;

  

  public class Main{

  

  public static void main(String[] args) {

      Scanner scn = new Scanner(System.in);

      int n = scn.nextInt();

      int sourceBase = scn.nextInt();

      int  destBase= scn.nextInt();

      

      int newN = convertNumber(n,sourceBase,10);

      if(destBase != 10)

        newN = convertNumber(newN,10,destBase);

        

      System.out.println(newN);

   }   

   public static int convertNumber(int n,int sourceBase,int destBase){

      int pow=1,newN=0;

      

      while(n>0){

          newN += (n%destBase) * pow;

          pow *= sourceBase;

          n/=destBase;

      }

      

      return newN;

   }

  }
