Any Base To Decimal | aCoding | Day 13

Problem:

1. You are given a number n.
2. You are given a base b. n is a number on base b.
3. You are required to convert the number n into its corresponding value in decimal number system.

Input Format

A number n
A base b

Output Format

A decimal number representing corresponding value of n in base b.

Constraints
0 <= d <= 1000000000
2 <= b <= 10
  
Sample Input
111001
2
Sample Output
57

Solution:

import java.util.*;

  

  public class Main{

  

  public static void main(String[] args) {

      Scanner scn = new Scanner(System.in);

      int n = scn.nextInt();

      int b = scn.nextInt();

      int d = getValueIndecimal(n, b);

      System.out.println(d);

   }

  

   public static int getValueIndecimal(int n, int b){

      // write your code here

      int pow = 1,newN = 0;

      

      while(n >0){

          newN += (n%10) * pow;

          pow*=b;

          n/=10;

      }

      

      return newN;

   }

  }
