Question
The language is Java
Write a program to convert a number in the binary system to a number in the decimal system in
recursive way.
The following is a hint:
Мbin ('O')
Mpin ('1')
%3D
Mbin (<bin num>'0')
= 2 *
Mpin
(<bin num>)
Mbin (<bin_ num>'1')
2 * Mpin (<bin num>)
+ 1
example:
Mbin ("10110")=2*Mbin ("1011")
=2* [2*Mbin ("101")+1]
=2* {2* [2*Mbin ("10")+1]+1}
=2* {2* [2* (2*Mbin ('1'))+1]+1}
=2* {2*[2* (2*1)+1]+1}
=2* {2* [2*2+1]+1}
=2* {2*5+1}
=2*11
=22
Use the data "1011001" to trace Java program and show the answer in base
10.
